Question

use the method of subsitution to solve the system of linear equations.
3x+y=-4
-2x+y=8

Answer 1

convert the second equation to y=8+2x, replace in first so
3x+(8+2x)=-4

Answer 2

solve for x , replace the found x value in any of the equations, and solve for y

Answer 3

x=-12/5, y=-4+36/5

Answer 4

how did you find the x and y value?

Answer 5

the x value I found by solving 3x+(8+2x)=-4,>> 5x+8=-4, >> 5x=-12...
the y i found by using the x value in the first equation
