 Question 245575: solve by the elimination method 0.5x+0.25y=66 0.15x+0.05y=72 Ijust do not understand this could someone help please? ThanksAnswer by checkley77(12569)   (Show Source): You can put this solution on YOUR website!0.5x+0.25y=66 multiply by -.3 & add. 0.15x+0.05y=72 -0.15x-0.075y=-19.8 0.15x+.05y=72 ----------------------- -.025y=52.2 y=52.2/-.025 y=-2088 ans. .5x+.25*-2088=66 .5x-522=66 .5x=66+522 .5x=588 x=588/.5 x=1,176 ans.
