To solve the equation undo the operations on the variable in reverse of PEMDAS
[tex]\frac{z}{5}-7+7=-1+7[/tex] this eliminates "S" subtract 7 with "A" add 7

[tex]\frac{z}{5}=6[/tex] Simplified both sides

[tex]5*\frac{z}{5}=5*6[/tex] this eliminates "D" divide by 5 with "M" multiply by 5
ANSWER z = 30
