Olivia wrote the following steps to solve a pair of equations: Step 1: y = −x − 3
y = 4x + 4

Step 2: 4y = −4x −12
y = 4x + 4
Which of the following shows the correct next step to solve the equations by eliminating x? (1 point)

a.5y = −3
b. 5y = −16
c. 5y = −48
d.5y = −8

597

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

i think it is 18
