Solving Equation Variables on Both Sides

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 the equation
4x - 5x + 9 =5x - 9

• x = -3

• x = 9

• x = 3

• x = -9

14p - 8 = 22 + 20p

• -5

• 5

• 30

• -30

What is the first step to solve this equation:

-11 - 3x = 44 - 2x

• Add 3 to both sides

• Get the variable on one side

• Add 11 to both sides

• Add 2 on both sides.

2x = x + 3

• 6

• 3

• 2

• x

7x = 3x + 24

• 6

• 10

• 14

• 4

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

• y = -4

• y = 9

• y = 4

• y = 36/19
