OpenStudy (katrinakaif):
6(z+8)=-8z-2
1)Distribute the 6 to (z + 8)
= 6z + 48 = -8z - 2
2)Bring -8z to the other side by adding 8z:
6z + 8z + 48 = -2
3)Bring +48 to the other sside by substracting it.:
6z + 8z = -50
4)Add like terms:
14z = 50
5) Divide by 14 on both sides and you should get your answer. Dont forget to simplify! :))

Distribute, add, group like terms, isolate varible, solve for variable. In that order, and you are done.

Thanks Kat
OpenStudy (anonymous):
\[6(z+8)=8z+2\]
\[6x+48=8z+2\]
\[48-2=8z-6z\]
\[46=2z\]
\[\frac{48}{2}=z\]
\[24=z\] all gory details spelled out

except that is was
\[6(z+8)=8z-2\]\ so my answer is wrong. should be
\[2z=50\]
\[z=25\]
OpenStudy (zarkon):
there is also a negative sign in front of the 8z
OpenStudy (anonymous):
then i should retire
