Jenna wants to solve the equation

What easier equation could she solve instead that would give her the same solution? (In other words, what equivalent equation has easier numbers to work with?)

Divide both sides by

. Justify that your equation in part (a) is equivalent to

by showing that they have the same solution. Solve both equations.

Now Jenna wants to solve

. Write and solve an equivalent equation with easier numbers that would give her the same answer. Multiply both sides by

and simplify. Remember to check your work.
