Question

(x + 3y = 2), (4x + 5y = 1) system of equations

Answer 1

first, make the first equation x=
x+3y=2
x=-3y+2
now plug that in for x in the second equation
4(-3y+2)+5y=1
-12y+8+5=1
-12y+13=1
-12y=-12
y=1
now plug y back into your x= equation
x=-3(1)+2
x=-1

(-1,1)

Answer 2

what about by elimination/addition?
