Solve for y: 
4x + 3y = 9

• y = -3/4x + 3
• y = -4x + 9
• y = -4/3x + 3
• 3y = -4x + 9

Solve for y:

3y -9 = 18x

• y=18x-3

• y=2x-3

• y=-26x+3

• y=6x+3

Solve for y
5x - y = 6

• y= 5x-6
• Y= -5X +6
• Y=5X+6
• Y=-5X-6

Solve for y:
7x+ 2y = 20

• y= 7/2x + 10
• y=-7/2x + 10
• y=2/7 x- 10
• y= -2/7x + 10

Scott works on cars. He charges $35 dollars a car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63
• 7x = 63
• 7x - 35 = 63
• 35x + 7 = 63

Write a equation:  A plumber charges $50 for a house call plus $12 per hour for labor.

• y = 50 x + 12
• y =12 x + 50
• y = 62 x
• x = 50 + 12y
