Question

Solve the systems using substitution.

6x + 2y = 0
4x + y = -1

Answer 1

solve the bottom equation for y

y=-1-4x

Answer 2

sub into first eqaution

Answer 3

6x+2(-1-4x)=0

6x+-2+-8x=0
-2x-2=0
-2x=2
x=-1

solve second equation for when x=-1

4(-1)+y=-1

-4+y=-1
y=3

so your solution set is (x,y)=(-1,3)
