Solving for X Y Constants

Solve the following equation for x:

5x − 6 = 8 − 2x

• x = 2

• x= −2

In order to solve an equation, we must get the variables on one side of the equation, and the constants on the other side.

• False

• True

• x=3

• x=1

• x=-1

• x=-4

We solve equations using___?

• fractions

• the distributive property

• inverse operations

• factors

4x + 10 = -26

• 4

• -4

• -9

• 9

8x - 6 = 2 (4x - 3)

• -3

• 3

• infinite solutions

• no solutions

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15

• 8

• 6

• 54

• 50

What is the first step in solving the following equation?

-3x + 5 = 20

• Subtract 5 from both sides

• Divide both sides by -3

• Divide both sides by 3

• add 3x to both sides

Solve:
8x + 4y = 16    ,  for     y

• y = -2x + 4

• y = 2x - 4

• y = 2x + 4

• y = -2x - 4
