Solve the following system of equations. y=2x+16
2x−7y=−64
Possible answers
-4,8 -1,11 -7,11

x = -4,      y = 8

Step-by-step explanation:

y = 2x + 16 (1)

2x - 7y = - 64 (2)

Substitute (1) in (2)

2x - 7(2x + 16) = - 64

2x - 14x - 112 = - 64

-12x = -64 + 112

-12x = 48

x = -4

Substitute x = -4 in (1)

y = 2(-4) + 16

y = -8 + 16

y  =8

It is -4,8.

Step-by-step explanation:

y=2x +16

{

-7y=-2x-64

-6y=-48

y=8 then using substitution you will get x=-4

ik how do do this just give me a few minutes and i will give it to

the value of x is 28.2
