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}
