Answer 2

Do you want anyone's help? or just dtan5457?

Answer 3

3x+2y=11
x-2=-4y

Substitution method is to isolate a variable, so that x=, or y=, then to plug into the other equation.

x-2=-4y
x=-4y+2

Plug that back into first equation

3(-4y+2)+2y=11

-12y+6+2y=11

solve for y

-10y=5

y=-0.5

Now you have your y coordinate.

Plug y=-0.5 into any of the 2 original equations to get x.

Your answer should be (x,-0.5)

Just solve for x.
