4(z-2)=20

Answer 1

To solve the equation 4(z-2)=20, we will use the distributive property first and then isolate the variable z.

First, let's distribute the 4:

4(z-2) = 20

4z - 8 = 20

Next, let's isolate the variable z. We will add 8 to both sides of the equation:

4z - 8 + 8 = 20 + 8

4z = 28

Finally, to solve for z, divide both sides of the equation by 4:

4z/4 = 28/4

z = 7

Therefore, the solution to the equation 4(z-2)=20 is z = 7.
