Answer:
x=(16-4y)/(3)

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:


3x +4y -4y=16-4y - Subtract 4y from both sides to get rid of it on one side.


3x=16-4y - Simplify the equation.


(3x)/(3) =(16-4y)/(3) - Divide both sides by 3 to isolate x.


x=(16-4y)/(3) - Simplify the equation again and you will receive your final answer.
