[tex]5(2+4z)=85[/tex]
Get Rid of ()'s. Now the equation will look like this:
[tex]10+20z=85[/tex]
Subtract [tex]10[/tex] from both sides. Now the equation will look like this: [tex]20z=75[/tex]
Now divided [tex]20[/tex] from both sides and you get:
Exact Form: [tex]\frac{15}{4}[/tex]
Decimal Form: [tex]z=3.75[/tex]
Mixed Number Form: [tex]3\frac{3}{4}[/tex]
