 Question 181875: I have tried this but I am having trouble, can you please help. Use substitution to solve each system. If it does not have one solution then put no solution or indinitely many solutions. 1/3X-Y=3 2X+Y=25 Answer by checkley77(12569)   (Show Source): You can put this solution on YOUR website!1/3X-Y=3 -y=-x/3+3 y=x/3-3 now replace y with (x/3-3) in the other equation 2X+Y=25 SORY I MISSED THE 2 IN FRONT O THE X. 2x+(x/3-3)=25 2x+x/3=25+3 2x+x/3=28 (2x*3+x)/3=28 (6x+x)/3=28 7x=3*28 7x=84 x=84/7 x=12 ans. y=12/3-3 y=4-3 y=1 ans. Proof: 2*12+1=25 24+1=25 25=25
