Question

Solve by substitution method:

3x+8y=33
x=31-6y

Answer 1

This is very simple. All you have to do is put what is equal to x in the second equation (31-6y) in for the x in the first equation giving you the equation 3(31-6y)+8y=33

Solve for the y with this equation then plug that answer into either of the equations to get x.
