Equation A
Equation B

Step 1. Let's get rid of the denominators in Equation B by multiplying by 18 to both sides of the equation

Equation B1

Step 2. Solving Equations A and B1 leads to the following steps by substitution

Solve:
We'll use substitution. After moving -2*y to the right, we get:
, or . Substitute that
into another equation:
and simplify: So, we know that y=-2. Since , x=0.333333333333333.

Answer: .

I hope the above steps were helpful.
