Solve Equations with Variables on One Side

3y+4y+6=20

• y=2

• y=-2

• y=4

• y=3

What is the first step in solving this equation?

• add 4 to both sides

• distribute the 4

• subtract 4 to both sides

• subtract 12 to both sides

What will the equation look like after you distribute?

• -6x - 8 = 10

• -6x + 8 = 10

• -5x - 6 = 10

• -5x + 6 = 10

What will the equation look like after you combine like terms?

• -5x + 5 = 35

• x + 5 = 35

• 5x + 5 = 35

• -x + 5 = 35

• x = 12

• x = -10

• x = -6

• x = -16

3(x + 5) – 6x = -18

4x + 10 = -26

• 4

• -4

• -9

• 9

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides

• Add the 2a and a 

• Distribute 4 to a and -5

• Distribute -4 to a and -5

-15 = 5a +12- 2a + 6

• -11

• -3

• 10

• 7

3a + 9 + 4a = 2

• -1

• 1

• no solution

• -7
