Question

Find the missing variable and check: 5(z+4)-13=2z+19

Answer 1

`5(z+4)-13=2z+19`

first solve the parenthesis

`5z+20-13=2z+19`

now place the z's on the same side and the numbers on the other side

`\begin{gathered} 5z-2z=19+13-20 \\ 3z=12 \\ z=(12)/(3) \\ \\ z=4 \end{gathered}`

the value of z is 4
