Answer:

z=2m+6

Step-by-step explanation:

3z+6(m-5)=-48\\6(m-5)+48=3z\\6m-30+48=3z\\6m+18=3z\\

\frac{6m+18}{3} =\frac{3z}{3}

2m+6=z

Answer:

<u>z = -2(m + 3)</u>

Step-by-step explanation:

Given :

  • 3z + 6(m - 5) = -48

Divide throughout by 3 :

  • 1/3 x (3z + 6(m - 5)) = -48 x 1/3
  • z + 2(m - 5) = -16

Subtract 2(m - 5) on each side :

  • z + 2(m - 5) - 2(m - 5) = -16 - 2(m - 5)
  • z = -16 - 2(m - 5)

Simplify the RHS :

  • z = -16 - 2m + 10
  • z = -2m - 6
  • <u>z = -2(m + 3)</u>
