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

\frac{z}{5}=6 Simplified both sides

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

Obviously, it's not rational, because it's the sum of two square roots, so cancel out A and B right away.

If we solve it
 
sqrt (18) + sqrt (2)
= sqrt (9*2) + sqrt (2)
= 3 sqrt (2) + sqrt (2)
= 4 sqrt (2)
