Question

Find the solution to the system of equations given below using elimination by addition.

5x + 20y = 60
x + 3y = 9

Answer 1

I think that the question asks you to form a simultaneous equation: 5x=60-20y x=12-4y
12-4y+3y=9
-y=9-12
-y=-3
y=3 and x=12-4y
Sorry if I misunderstood the question
