Question

Solve the following system of linear equations by substitution:
6x+6y=12
3x+3y=6

Answer 1

All points along:
y=2-x
are solutions.
6x+6y=12 ==> y=2-x
3x+3x=6 ==>y=2-x

Answer 2

I did what I wrote, I solved both in terms of y and found they are the same thing...
you could tell this was going to be the solution because both sets of equations had equal multiples of the intercept as their binary variable constants
