The previous answer is right but didnt finish the problem.
Break it Down:
2(X+5)-3=0
2x + 10 - 3 = 0
2x + 7 = 0
2x = -7
x = -3.5

twice the sum of a number and 5 is 2(x + 5)
so, a quantity that is three less than that is 2(x+5) - 3

quantity three less than twice the sum of a number and 5?
You mean 2n + 5 - 3? = 2n + 2 = 2(n + 1)

If x is the quantity and the number being summed with 5 is y, the answer is: x=2y+13
If x and y are the same number, the answer is -13.
