Whats the solution set for 2x+y=6, y=2x-4

Answer 1

y=6-2x

y=2x-4

6-2x=2x-4

4x=10

y=5/2 and y=1

Answer 2

Given the way you have written the equations. Substitute 2x-4 for y in the first equation.

Solve for x.

Then use either equation to solve for y by plugging in the x that you got.

Plug both values into the other equation in order to check your answer.
