Equations

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5
• Subtract 5
• Multiply by 7
• Subtract 7

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

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

• 4
• 3
• 2
• 1

-(n - 8) = -2

• 6
• 10
• -10
• -6

Solve for x: 17x - 11x = 18

• 6x = 18

• x = 3

• x = -3

Solve for t: 5t - 4t = 5

• t = 5

• t = 5/9

• t = -5

3x=33

• x=11

• x=99

• x=30

• x=36

7x - 4x = 27

• x = 9
• x = 27/11
• x = 11/27
• x = 1/3

6x - 5 + 7x = 34

• x = 31
• x = 31/13
• x = 3
• x = -31

-15 + 3x - 7x = -43

• x = 7
• x = -7
• x = 58/4
• x = -14/5
