replace y in the second equation you get x
then replace x in anh equation and you'd get get y
Supernova
Take y = 3x - 5 and plug it into the equation below.
6x + 3(3x - 5) = 15. Solve for x.
6x + 9x - 15 = 15
15x = 30
x = 2
Now plug x back into the equation y = 3x - 5.
y = 3(2) - 5.
y = 6 - 5 
y = 1
