Answer:

Explanation:
- We want to isolate for x, meaning x must be the only variable on one side of the equation
- Simplifying an equation would mean to write it in its simplest form which in this case would be when x is by itself.
Calculations:
- Subtract 4y from both sides to get rid of it on one side.
- Simplify the equation.
- Divide both sides by 3 to isolate x.
- Simplify the equation again and you will receive your final answer.
