Question

Solve for z. 18 = 3(z – 8)

Answer 1

Given the expression:

`18=3(z-8)`

notice that we can move the 3 that is multiplying the factor z-8 to the left dividing the constant 18:

`\begin{gathered} 18=3(z-8) \\ \Rightarrow(18)/(3)=z-8 \\ \Rightarrow6=z-8 \end{gathered}`

now we can add 8 on both sides of the equation to get the following:

`\begin{gathered} 6+8=z-8+8 \\ \Rightarrow14=z \end{gathered}`

therefore, z = 14
