:
a. Solve for x
Get rid of the brackets, square everything inside the brackets

Subtract 7 from both sides
3x =
divide both sides by 3
x = -
:
;
b. solve for y
Get rid of the brackets, square everything inside the brackets

multiply both sides by z^2

divide both sides by 16
=
Find the square root of both sides
= y

:
c. Solve for z

multiply both sides by z^2

divide both sides by (3x+7)

Find the square root of both sides
z =
