The absolute value of the sum of -7 and twice a number is 23 . find the number
~~~~~~~~~~~~~~~~~~~~~~~~

The Math translation of the condition is this equation |-7 +2x| = 23. // Notice it is DIFFERENT from that of @josgarithmetic, which is W R O N G. EITHER a) -7 + 2x = 23 ====> 2x = 23+7 = 30 ====> x = 15, OR b) -7 + 2x = -23 ====> 2x = -23 + 7 = -16 ====> x = -8. Answer. The original equation has two solutions: x = 15 and/or x = -8.

Be aware: the solution and the answer by @josgarithmetic both are W R O N G.

Simply ignore it . . .
