What is the solution to the system of equations?
y=2x+6 3x-y=6 **Weegy:** The solution set for y = 2x + 6, 3x - y = 6 is {x = 12, y = 30}.
Solution:
3x - 2x + 6 = 6;
x - 6 = 6;
x = 6 + 6;
x = 12;
y = 2x + 6;
y = 2(12) + 6;
y = 24 + 6;
y = 30 (More)

y – 2x = 8 we get y = 2x + 8 (equ 1)

16 + 4x = 2y (equ 2)

using equ. 1 to substitute y in equ. 2 the result is:

16 + 4x = 2(2x + 8)

16 + 4x = 4x + 16

4x - 4x = 16 - 16

0 = 0

There are infinitely many solutions for the equation system y – 2x = 8 16 + 4x = 2y

16 + 4x = 2y (equ 2)

using equ. 1 to substitute y in equ. 2 the result is:

16 + 4x = 2(2x + 8)

16 + 4x = 4x + 16

4x - 4x = 16 - 16

0 = 0

There are infinitely many solutions for the equation system y – 2x = 8 16 + 4x = 2y
