4b+2c=36, solve for b, subtract 2c from both sides
4b=36-2c divide both sides by 4
b=9-0.5c
Then we are told that:
7b+3c=59, using b=9-0.5c we get:
7(9-0.5c)+3c=59 perform indicated multiplication on left side
63-3.5c+3c=59 combine like terms on left side
63-0.5c=59 subtract 63 from both sides
-0.5c=-4 divide both sides by 0.5
c=8
