What is the proper set up to solve the equation?

-7x -2y= -13

x = 2y+11

• -7(11) -2y = -13

• -7(2y +11)-2y = -13

• -7x -2(11) =-13

• -7x - 2(2y+11)= -13

Judy is saving to buy a pair of shoes that cost $120. She has saved $30 and is going to save $25 a week. Which equation will show her how many weeks she must save?

• 120 = 25x + 30

• 120 = 55x

• 120 = 25x + 30x

• 25x = 120 + 30
