Solve:

2(2x + 3) = -6(x + 9)

• 2

• 6

• -6

• 7.5

Solve:

7x + 19 = -2x + 55

• 4

• 14.8

• 8.2

• -4

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

• x = 5/3

• x = 3

• x = 1

• x = 2

-19 = -8 (-4+a) - (2a+1)

• -1

• 14

• -5

• 5

Solve:
5y + 34 = -2(-7y+1)

• y = -4

• y = 9

• y = 4

• y = 36/19

What is the error?

• Adding 2x to 3x

• Subtracting 5 from both sides

• Adding 2x to -2x

• Dividing by 5 on both sides
