Question

Solve by Substitution Method.
2x-5y=-1
x - 3y=-3

Answer 1

From equation 2, x= -3 + 3y
Substitute this into equation 1, we get 2(-3+3y)-5y=-1
-6+6y-5y=-1
y=-1+6
y=5

Answer 2

Substituting y=5 back into equation 2, we get
x - 3(5) = -3
x - 15 = -3
x = -3 + 15
x =12

Answer 3

Therefore solutions are, x=12 , y=5

Answer 4
