A Bag of candy contains 19 watermelon candies, 22 sour apple candies, and 17 cherry candies. The rest of the candies are grape. There are 87 candies in the bag. If G represents the number of grape candies, what equation could you use to find G? A. G- 58 = 87 B. 58 ÷ g = 87 C. 58g= 87 D. 58+ g=87

D is the answer

Step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
