Solving Equations

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

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

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

Solve for x.

• x = 21
• x = 7
• x = −21
• x = 4

Solve: x + 3x - 2x = 12

• 2
• 6
• -2
• -6

2x + 3(5x - 7) = 47

• x = 1
• x = 2
• x = 3
• x = 4

-4 + w = -6

• w = -2

• w = -10

• w = 2

• w = 24

7 = 6w + 34 + 3w

• w = 3

• w = -3

• w = -9

• w = 9

15 = 9w - 6w

• w = 1

• w = -5

• w = 5

• w = -1

5x - 4 + 2x = 3

• 1
• 2
• 3
• 4

Solve:
3x + 7 = -8

• 5
• -5
• -12
• -18
