Question

eight less then a number doubled is twenty more then the number. What is the number ?
a.28 b.6 c.14 d.36

Answer 1

8 less than "a number" can be represented as x (the number) -8.

8 less than "a number doubled" would be 2*x-8.

So 2x-8 equals x (the number) plus 20 more, or 20+x.

Isolate x, and it equals 28
