How do you solve the equations below?

-2x+4y=-8

x-2y=1

You can solve it by substitution or elimination.

Step-by-step explanation:

-2x+4y=-8

x-2y=1

Im gonna use substitution because it seems easier with the numbers given.

To do so you have to solve for a variable i solved for x in the second equation.

x-2y=1

+2y + 2y

x=2y+1

You have to plug this into the x in the other equation.

-2 (2y+1) = -8

Simplify the equation by using the distributive property.

-4y-2=-8

isolate the variable:

+2 + 2

-4y=-6

isolate the variable by using division.

y=-6/-4

y=3/2

Plug this into the y of one of the equations and solve for the x.
