3e + 4b = 485
5e + 3b = 460 Multiply this equation by - 1 1/3 to get
-20/3 e - 4b = - 613 1/3 add this equation to the top one (see how we eliminated the 'b' variable?)
-11/3 e = -128 1/3
e = 128 1/3 x 3/11 = 35 cents
SUb this value into one of the equtions to find the value of b
3(35) + 4b = 485
b = 95 cents
