Question

X - 3y = 1 3x - 5y = 11

Answer 1

The answers are...
x=7
y=2

Answer 2

I would isolate x in the first equation:

x = 3y + 1

For the second equation, you could just substitute the x inside:

3x - 5y = 11
3(3y +1) - 5y = 11
9y + 3 - 5y = 11
4y + 3 = 11
4y = 8
y = 2

Using the y = 2, we can find x.

x = 3y + 1
x = 3(2) + 1
x = 7

x = 7 and y = 2
