Math Unit 2 Reflection

By Mark Calloway

Introduction

Unit 2 has these three equations: One step; two step; and three step equations. One step equations only need one step to solve them. Two step equations need two steps two solve them. Three step (multiple step) equations need 3 or more steps to solve.

One Step Equations

A one step equations only needs one step to solve it. You need to cancel out the number and not the variable. For example, if the problem was r plus 12 equals 25, than you would subtract 12 from both sides, which leaves you at r equals 13.

Two Step Equations

Two step equations need two steps to solve, and are more complicated. You need to subtract or add the number from both sides, then multiply or divide the number with the variable from both sides. For example, -3x plus 4 equals 16. Subtract 4 from both sides, which leaves you with -3x equals 12. Now, you divide both sides by -3, which gives you x equals -4

Three Step Equations

Three step equations need 3 or more steps to solve. Sometimes you need to distribute, and other times you need to add like terms. In a three step equation, there are 2 or more factors on each side of the equal sign. For example, 3x plus 5 minus 5 equals 20 minus 5. First you need to subtract 5 from each side, including 20. Now you have 3x equals 15. Next, you divide each side by 3, which gives you x equals 5.

Closure

The more steps an equation has, the more complicated it will be. Unit 2 has gone over one step, two step, and three step equations.
