Linear Equations

Solve for x:
2x + 5 = 12

• 7
• 3
• 3.5
• 8.5

• 9

• 2

• 18

• 3

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.

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.

Solve for x: 
4x + 1 = 7x - 5

• -1
• 2
• 6/11
• 8

Solve for x:
6(2x + 1) = 18

• 3
• 17/12
• 1
• 2

Solve for x if x + 5 = 9

• x = 5

• x = 4

• x = 15

• x = -14

What is the value of x if x - 6 = 5

• x = 11

• x = 1

• x = 2

• x = 30

19  + a  =  -50

• a = -950
• a =  -69
• a = -31
• a = -50/19

Solve the following equation,
