Question

Solve this system of equations using substitution. Put your answer in ordered pair form, (x, y). x + 3y = 2 2x - 3y = 22

Answer 1

Solve this system of equations using substitution. Put your answer in ordered pair form, (x, y).

x + 3y = 2
2x - 3y = 22

Answer 2

x+3y=2
2x-3y=22
x+3y=2,x=2-3y
substitute in 2x-3y=22,we get
2(2-3y)-3y=22
or 4-6y-3y=22
-9y=22-4=18
y=18/-9=-2
hence x=2-3(-2)=2+6=8
solution is (8,-2)
