 Question 641901: hi I can't remeber exactly how to do this problem. Solve using substitution method: 15x-10y=1 5y=-1+10x I tried this: 5/y=-1+10/5 then (5)15x-(5)10(5)(-1+10x/5)=1(5) 75x-50(-1+10x)=5 75x+50-500x=5 425x=45 it just dosen't look rightAnswer by jim_thompson5910(29613)   (Show Source): You can put this solution on YOUR website!5y=-1+10x 2*5y=2*(-1+10x) 10y = -2+20x ------------------------------------------------------- 15x-10y=1 15x-(-2+20x)=1 15x+2-20x = 1 -5x+2 = 1 -5x = 1-2 -5x = -1 x = -1/(-5) x = 1/5 Now use this to find y.
