 Question 634494: When i try the solvers and choose elimination it automatically goes to substitution, i need both in order to complete the problem...i Dont know how so i cant complete the rest of the page! 3x - 5y = 7 2x + 5y = 13 Thank You!Found 2 solutions by richwmiller, stanbon:Answer by richwmiller(9143)   (Show Source): You can put this solution on YOUR website!You add the two equations which gives 5x=20 x=4 now you do substitute 4 for x and solve for y 12-5y=7 subtract 12 -5y=-5 divide by -1 y=1 Answer by stanbon(57377)   (Show Source): You can put this solution on YOUR website!3x - 5y = 7 2x + 5y = 13 ---- Multiply thru 1st by 2. Multiply thru 2nd by 3. ------ 6x - 10y = 14 6x + 15y = 39 ----- Subtract and solve for "y": 25y = 25 y = 1 ---- Solve for "x": 3x - 5y = 7 3x - 5*1 = 7 3x = 12 x = 4 --------- Cheers, Stan H. ===========
