Solve for f:
f - 4 = 6f + 26

• f = -5

• f = 5

• f = 6

• f = -6

Solve for x:
5x - 14 = 8x + 4

• x = 6

• x = -6

• x = -18/13

• x = 10/3

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

• y = -4

• y = 9

• y = 4

• y = 36/19

What is the second 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
