These equations do match up. All you have to do is find the solution to the first equation. After that, plug in that solution to the second equation. If it makes the equation true, then the equations match.
5 x + 3 y = 41 / * 3 3 x + 2 y = 26 / * ( - 5 ) ----------------------------- 15 x + 9 y = 123 + - 15 x - 10 y = - 130 --------------------------- - y = - 7 / * ( - 1 ) y = 7 Answer: Each program costs D ) $7
