Step-by-step explanation:
Let x and y represent push-ups and pull-ups, respectively.
x + y = 24 . . . . . . combined total of push/pull-ups
2x +4y = 68 . . . . time required for the exercise
We can divide the second equation by 2 and subtract the first:
(1/2)(2x +4y) -(x +y) = (1/2)(68) -(24)
x +2y -x -y = 34 -24 . . . . . eliminate parentheses
y = 10 . . . . . . . . . simplify
