Which part of the equations concern you? What is your question?
3 x - 2 y=7y
2 x - 1 = 7 y
????
3 x = 5 y
x = (5/3) y
10/3 y - 1 = 7 y
-1 = 11/3 y
y = -3/11
x = (5/3)y = -5/11
2 x - 1 = 7 y
????
3 x = 5 y
x = (5/3) y
10/3 y - 1 = 7 y
-1 = 11/3 y
y = -3/11
x = (5/3)y = -5/11
Woops, immediate dumb error
3 x = 9y so x = 3 y
2 x - 1 = 7 y
6 y - 1 = 7 y
y = -1
x = -3
3 x = 9y so x = 3 y
2 x - 1 = 7 y
6 y - 1 = 7 y
y = -1
x = -3
