I believe you haven't included the system of equations for us to solve.
However, I will tell you that you need to solve for one variable in an equation and substitute that into the other equation.
For example:
x = yz; z = x/y
a = zb; a = (x/y)b

Answer:
x=3
Step-by-step explanation:
The approach is not very different from regular fractions.
You have to get to a common denominator to be able to add them.
10 is a good denominator (multiply the denominators).
multiply the first term by 5, and the second one by 2:



7x + 9 = 30
7x = 30 - 9
x = 3
