Solving Linear Equations

Solve the equation:
-5x = 25

• x = 20
• x = -20
• x = -5
• x = 5

19  + a  =  -50

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

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 for x:
12 = 20x - 18

• 1
• -2
• -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.

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
