Solving Equations with Variables on One Side

Solve:
5y+34 = -2(-7y+1)

• y = -4

• y = 9

• y = 4

• y = 36/19

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.

Solve: 5x - 14 = 8x + 4

• 6

• -6

• -18/13

• 10/3

-(8n - 2) = 3 + 10(1 - 3n)

• n = 1/2

• n = -1/2

• n = 2

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

Solve for a:

9+2a = -3-4a

• a=5

• a= -1

• a= -2

• a=2

30 + 6t = 11t

• 3

• 5

• 6

• 30

5 - 2t = 3t

• 1

• 5

• 3

• 2

6z = 49 - z

• 49

• -7

• 6

• 7

n - 1 = -11

• 5

• 10

• -10

• -11
