Andrei [34K]

Answer:

x=3z+5

/z^2

Step-by-step explanation:

Let's solve for x.

xz^2−3z−5=0

Step 1: Add 5 to both sides.

xz^2−3z−5+5=0+5

xz^2−3z=5

Step 2: Add 3z to both sides.

xz^2−3z+3z=5+3z

xz^2=3z+5

Step 3: Divide both sides by z^2.

xz^2

/z^2

=

3z+5/

z^2

x=

3z+5

/z^2

Answer:

x=3z+5

/z^2
