Best ResponseYou've already chosen the best response.1Use substitution. Equation1 2x5y=8 Solve for x, 2x=8+5y, then x=4+(5/2)y Equation 2, 7x=6y=17, substitute the newly found x expression like this; 7(4+(5/2)y)+6y=17 this becomes 28+35/2y+6y=17 consolidating similar terms 47y/2=11 now solve for y

Best ResponseYou've already chosen the best response.0I think it's much easier just to add the two equations, since they sum up to: 9x+y=25
