fabulousflamingBananas cost: $0.25 Apples cost: $0.30 4b+5a=2.50 10b+3a=3.40 You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have 12b+15a=7.50 50b+15a=17 Subtract them and end up with -38b=-9.5 solve: b=0.25, substitute b in any equation and get a=0.30 Hope this helped
