If you would like to solve the following system, you can calculate this using the following steps:
y = x - 20
y = 6 x
_________
6 x = x - 20
6 x - x = -20
5 x = -20 /5
x = -4
y = 6 x = 6 (-4) = -24
If you would like to solve the following system, you can calculate this using the following steps:
y = x + 20
y = 6 x
_________
6 x = x + 20
6 x - x = 20
5 x = 20 /5
x = 4
y = 6 x = 6 4 = 24
