Solving Linear Equations

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

The first step to solving the equation g - 3 = -12 is to . . .

• divide by -3 on both sides of the equal sign

• multiply by -3 on both sides of the equal sign

• subtract 3 on both sides of the equal sign

• add 3 on both sides of the equal sign

Solve the equation:

7x = 21

• x = 14

• x = 28

• x = 3

• x = 147

Solve for the value of y:

y - (-3) = 9

• y = 12

• y = 6

• y = 3

• y = 9

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

18+m=8

• m=0
• m=10
• m=-10
• m=8

-4x + 1 = 21

• x=120
• x=5
• x=30
• x=-5

144=12z

• z=20
• z=11
• z=12

3x - 5 = -26

• x=-21

• x=21

• x=-7

• x=61

Solve for k:
3k + 5 = 23

• k = 4
• k = 5
• k = 6
• k = 7
