7. Sadly, we have reached the end, the last warm-up
question of the year..........

8. 5x  1  3x 5  2.
Set up the equation
so that there will be
only one radical on
each side of the equal sign.
Square both sides
of the equation.
Simplify.
Simplify by dividing
by a common factor of 2.
Square both sides of the
equation.
