For each equation below, solve for the variable. Check your solutions, if possible, and show all work.
For more help with parts (a) - (d), see the equation mat in problem 2-105.
First, try rewriting all of the subtraction as addition, then attempt to solve by simplifying like terms.
One strategy is to rewrite all of the subtraction within the problem as addition.
Now simplify, starting with combining like terms and then with isolating the variable.
