Solving the Linear Equations

Solve for x:
12 = 20x - 18

• 1

• -2

• -1

• 2

Solve the equation:
-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

3x - 5 = -26

• x=-21

• x=21

• x=-7

• x=61

Solve: 3(x-4) = -3

• 3

• -3

• 5

• -5

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: -7(z - 6) = -70

• 16

• -16

• 8

• -1/2

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

A toy company spends $1500 per day for factory expenses plus $8 to make each teddy bear.  They sell the teddy bears for $12 a piece.  Which equation could be used to find the number of bears t the company has to sell in one day to equal its daily cost?

• 1500 + 8t = 12

• 12 + 8t = 1500

• 1500 + 8t = 12t

• 8t = 12t + 1500
