2c + b = 37 ....multiply by -3
4c + 3b = 81
------------------
-6c - 3b = - 111 (result of multiplying by -3)
4c + 3b = 81
------------------add
-2c = - 30
c = -30/-2
c = 15 <== $ 15 for a can of paint
and it costs $ 7 for each brush
3x-6y=18
We need to get y by itself so first, subtract 3x from both sides
-6y= -3x+18
Now divide both sides by -6
y= 1/2x-3
