Hi there!

We can begin solving by creating a common denominator:
x · 3 · z = 3xz. This is the denominator that all of the numerators must have in order to work with the fractions.
Multiply each numerator by the missing parts of the common denominator:

Simplify:

Move all the fractions involving x in the numerator to the right-hand side of the equation:

Combine fractions:

Multiply both sides by 3xz:

Factor out "x" from the terms on the right-hand side:

Divide both sides by (18 + yz)
