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.
