On this page, you will find Algebra worksheets mostly for middle school students on algebra topics such as algebraic expressions, equations and graphing functions. This page starts off with some missing numbers worksheets for younger students.
As you begin solving equations in Algebra, the very first thing that you will learn is that whatever you do, you MUST keep your equation balanced!
It truly is the number one factor in solving equations! You will see step-by-step how equations are kept balanced for every example in this unit! In the explanations, you will see the words: Whatever you do to one side of the equation, you must do to the other side!
Those are the key words for balancing equations! Let's take a look at a graphic to give you a better understanding. Think of a scale that you would use to weigh things!
If you put a 5 lb weight on the left side, what happens? Is the scale balanced?
What would you have to do to balance it perfectly? You'd have to put another five pound weight or something that weighs five pounds on the other side. That's the only way it will stay balanced!
Think of the equation sign as the "center" of the scale. Take a look at the picture above, and imagine two 5 lb weights on the left side, and two 5 lb weights on the right side. How much weight is on each side? So, right now the scale is balanced! Now, what happens if I take 5 lbs off of the right side?
Is the scale balanced now? No, there's 10 lbs still on the left, but only 5 lbs on the right. So, what must I do to keep it balanced? I must ALSO take 5 lbs off of the left! Now, it is balanced again! So, in Algebra if you subtract 5 from one side, you must also subtract 5 from the other side.
Why have I continued to repeat those same words? You will see those words in all of my explanations, so look for them!
Keep those equations balanced and you will do well!Practice solving one-variable equations like 20 - 7x = 6x - 6, where the variable appears on both sides of the equals sign. Practice: Equations with variables on both sides: decimals & fractions.
Equation with the variable in the denominator. Next tutorial. All: Solve equations with variable on one side (L5/6) Most: Solve equations with variable on both sides (L6) Some: Solve inequalities and show on number line (L7) Included: Starter worksheet to assess prior knowledge, 5 differentiated worksheets based on stage of prior learning, plenary worksheet to assess progress, powerpoint with outcomes/AFL Qs on, lesson plan.
Multi-step equations are all equations that require you to perform more than two steps (or operations) in order to solve them.
They can be simple or really hard to do, since there are no limitations on the number of steps you have to perform to get to a solution. Natural law theory is a legal theory that recognizes the connection between the law and human morality. This lesson explores some of the principles of the natural law theory, as well as provides.

Tip # 1: When you are trying to balance the chemical equations, you should remember that you can only change the value of coefficient in front of the element or compound, and not the subscript.
