Answer: x=14
Step-by-step explanation:Simplify both sides of the equation(Distribute),Subtract 4/5 from both sides.Multiply both sides by 5/(-1).
Substitution.
Here is an example.
Let x be equal to 3 and y equal to 3.

From this we can conclude that the values of both x and y are equal to three therefore x and y have the same value and are equal.

Here in your case we have:
