Solving Linear Equations

Solve for k:
3k + 5 = 23

• k = 4

• k = 5

• k = 6

• k = 7

Solve: 3(x-4) = -3

• 3

• -3

• 5

• -5

Solve:
2(4x - 3) - 8 = 4 + 2x

• x = 5/3

• x = 3

• x = 1

• x = 2

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.

19  + a  =  -50

• a = -950

• a =  -69

• a = -31

• a = -50/19

x - 8 = -5 

• 13

• -13

• 3

• -3

Which equation has x = 5 as the solution?

• x + 15 = 10

• 2x = 5

• 2x = 10

18+m=8

• m=0

• m=10

• m=-10

• m=8

144=12z

• z=20

• z=11

• z=12

-4x + 1 = 21

• x=120

• x=5

• x=30

• x=-5
