A system of pulleys is loaded with 192-pound and 64-pound weights (see figure). The tensions t1 and t2 in the ropes and the acceleration a of the 64-pound weight are found by solving the system of equations

where t1 and t2 are measured in pounds and a is in feet per second squared. Use Cramer's Rule to find t1, t2, and a.
