Answer:

NO solution

Explanation:

You must isolate by substitution to solve this problem.


\sf{2x-2y=14 \quad x-y=2}

Separate by x and y from one side of the equation.

Solve with 2x-2y=14, first.

2x-2y=14 which is equal to x=7+y.

Substitute x=7+y.


\sf{7+y-y=2}

Then you solve it.

You only need to cross out the variable y.

7=2

NO solution.

Therefore, a solution cannot be found.

I hope this helps! Let me know if my answer is wrong or not.
