    just substitute x=3/8 and y=-1 into the equation. if it equal to 10, then (3/8,-1) a solution.

    u hav (3/8,-1) and equation: 8x-7y=10 substitute x and y, u wil hav: 8(3/8)-7(-1)=10. this implies 3+7=10 => 10=10 since the equations holds for (3/8,-1), hence it is a solution for the equation.
