3.5 More on Solving Equations

Goal:

- To solve equations by first getting all variables to the same side of the equation

Steps to solve multi-step linear equations

- If there are ( ) distribute
- Collect like terms on same side.
- Move variables to same side of equation. (APE)
- Move the constant to the other side of the equation (APE)
- Solve for x using the (MPE)

+ 3x

+ 3x

- Eliminate the variable from one side using the Addition Property of Equality

2x – 2 = -3x + 3

5x – 2 = + 3

+3m

+3m

-5

-5

- Collect like terms on the same side first
- Eliminate the variable from one side using the Addition Property of Equality

6m +5 – 2m = 10 – 3m +16

4m +5 = 26 – 3m

7m +5 = 26

7m = 21

m =3

+3m

+3m

-5

-5

6m +5 – 2m = 10 – 3m +16

4m +5 = 26 – 3m

7m +5 = 26

7m = 21

m =3

3n - 6 – 1 = 2 – 5(n + 5)

3n - 6 – 1 = 2 – 5n - 25

3n - 7 = -23 – 5n

5n +

+5n

8n - 7 = -23

+7

+7

8n = -16

n =-2

3(2y +7) = 30 + 7(y - 1)

You try this one and raise your hand once you get the answer!

y = -2
