Question

Solve:
x+y=5
2x-3y=0

Answer 1

x=5-y

so sub this into the second equation.

2(5-y) - 3y = 0
10-2y - 3y = 0
10 - 5y = 0
10 = 5y
2 = y

Answer 2

what is x?

Answer 3

sorry, just put y = 2 into the first equation..

so.. x = 5 - (2) = 3

Answer 4

You know that y=2 right so...
You plug it into the equation x=5-y
Which will become x=5-2
