Question

Twice the sum of a number and 3 is the same as 5 subtracted from the number. find the number.

Answer 1

Translating this sentence into symbols:  2(x+3) = x - 5

So 2x + 6 = x - 5                    and x = -11

Check:  Is 2(-11+3) = -11 -5?               Is -16 = -16?  YES.  x =-11 is right.
