X= # of sodas sold
x - 42 = # of hot dogs sold
x+x-42=202
2x = 244
x=122
122 sodas and 80 hot dogs
he example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value...
