Question

Solve 5(z + 6) – 2 = 9z

Answer 1

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

Answer 2

Distribute, so 5z+28+9z, then subtract 5z, and you get 4z=28. Divide by 4 so x=7
