Solving Equations (Alg)

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

5m = 10  solve for m

• 50
• 15
• 5
• 2

Solve for the missing variable:

• m = 5
• m = 1/5
• m = 25
• m = 55

x - 16= 15

• 2

• 0

• -1

• 31

Solve the equation:

5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

• divide by 9 on both sides

• add 9 to both sides

• subtract 9 from both sides

m - 5 = 10

• -15

• 15

• -5

• 5
