Answer:z=13
Step-by-step explanation:To check just plug it back in and it will fit.3(z−8)+10=−5
Step 1: Simplify both sides of the equation.
3(z−8)+10=−5
(3)(z)+(3)(−8)+10=−5(Distribute)
3z+−24+10=−5
(3z)+(−24+10)=−5(Combine Like Terms)
3z+−14=−5
3z−14=−5
Step 2: Add 14 to both sides.
3z−14+14=−5+14
3z=9
Step 3: Divide both sides by 3.
3z
3
=
9
3
z=3
