X = 20 - y
7x - 12 =y
Using the two equations above, solve for y.
A = 24
B. y = 16
c.
y=4
D.
= 64
need help

B.  y = 16.

Step-by-step explanation:

x = 20 - y

7x - 12 = y

Rearranging both equations

x + y = 20A

7x - y = 12B       Adding A + B:

8x + 0 = 32

x = 32/8 = 4.

Substituting x = 4 in equation A:

4 + y = 20

y = 16.

Checking the results in the original equations:

x = 20 - y

4 = 20 - 16 = 4    Checked.

7x - 12 = y

7(4) - 12 = 16

28 - 12 = 16 Checked.
