2x+3y=38
what is x and y

Answer 1

♥ {x,y} = {4,10} (X=4,Y=10)
♥ To solve replace x and y
♥ so for the first equation it would be
♥ 4+10=14 and that's true
♥ and for the second you have
♥ 2*4+3*10=38 so once again true.

Answer 2

using the systems of equations, make the equation equal to
-2x-2y=-28
2x+3y=38
---
y=10
x=4
