Question

What are the x and y values in this system of equations ?
2x + 4y = 8
2x = x + 8

Answer 1

correction : 2y = x + 8

Answer 2

2x = x + 8
2x - x = 8
x = 8
sub x = 8 into equation one
2(8) + 4y = 8
16 + 4y = 8
4y = 8-16
4y = -16
y = -16/4
y = -4

Answer 3

so , how could you solve for the other value ?

Answer 4

x = 8 and y =-4 we both values.

Answer 5

8 isn't one of the answer choices.

Answer 6
