Question

What is the solution of the system of equations? y= -2x+8 y= x-4

Answer 1

X=4, y=0 my answer is too short but I'm to lazy to type the whole pr0cess

Answer 2

We can solve by substituting x-4 for y in the first equation.
x-4 = -2x+8
3x = 12
x = 4

Then plug in 4 for x in one of the equations.
y = 4-4
y = 0
OR
y = -2(4)+8
y = -8+8
y = 0

So the solution is (4,0)
