Answer:
z=7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(z+6)−2=9z
(5)(z)+(5)(6)+−2=9z(Distribute)
5z+30+−2=9z
(5z)+(30+−2)=9z(Combine Like Terms)
5z+28=9z
Step 2: Subtract 9z from both sides.
5z+28−9z=9z−9z
−4z+28=0
Step 3: Subtract 28 from both sides.
−4z+28−28=0−28
−4z=−28
Step 4: Divide both sides by -4.
−4z/−4=−28/−4
z=7
