We must find a solution where

Consider the Left Side:
First, to add fraction multiply each fraction on the left by it corresponding denomiator and we should get

Which equals

Add the fractions

Simplify the right side by multiplying the fraction

Set both fractions equal to each other

Since the denomiator are equal, we must set the numerator equal to each other





Answer:
Step-by-step explanation:
2. Should be 500
8. Should be 290
The rest are correct
Start with

Simplify the left hand side by summing like terms (the one involving z):

Subtract 5z from both sides:

Subtract 7 from both sides

Divide both sides by 11:

Answer:
