Question

The sum of twice a number and 11 less than the number is the same as the difference between -39 and the number.

Answer 1

64 is the number

Explanation:

Set up in numerical terms (using x as unknown #):

2x + (x-11) = x-(-39)

Isolate and solve for x:

2x = 50

x = 25

Check solution:

2(25) + (25-11) = (25) - (-39)

50 + 14 = 25 + 39

64 = 64
