Question

Eight less than a number doubled is twenty more than the number. What is the number?

Answer 1

X*2-8=20+x
Add 8 to both sides
2x=28+x
Subtract x from both sides
1x=28
X=28

Answer 2

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
