Solve Equations Variable on Both Sides

8 - 9t = 21t - 17

• t = 6/5
• t = 5/6
• t = 1

14p - 8 = 22 + 20p

• -5
• 5
• 30

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:
7x - 4 = 3 + 8x

• x = 7
• x = -7
• x = 2/7
• x = 11

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

What is v?
-15v-40 = 23-8v

• v = 9
• v = -7
• v = -9
