Answer:

x = {2, 5}

Step-by-step explanation:

Please include the instructions for each problem.  I will assume that they say “solve the following equation for x.”

By combining like terms, we get 2x^2-14x+27=7 => 2x^2 – 14x + 20 = 0

and this simplifies to x^2 – 7x + 10 = 0.

This can be rewritten as (x – 2)(x – 5) = 0, which yields x = {2, 5}
