: : : 1. X+Y=44
: : : Y=2(X-A)
: : : Y-A=(X+B/2
: : : X+B= 3(Y-C)
: : : Y-C= 3(X-C)

: : : Solve for X and Y in terms of A, B, and C.

: : : 2. Maddux, Smoltz, and Wohlers pitched a total of 576
: : : innings. Maddux pitched 8 2/3 fewer than Smoltz and
: : : 167 2/3 more than Wohlers. How many did each pitch?

: : : 3. 2 ladders are crossed in an alley. They are

: : : peel weigh?

: : : Please give a detailed explanation with each. Thanks for your assistance.

2. M+S+W= 576 is all I could figure out.

3. I have no idea where to start.
