The Numbers     Expressions
first            x
second           x+10
third            4(x+10)
SUM               92

x%2B%28x%2B10%29%2B4%28x%2B10%29=92---------solve and then evaluate the other two expressions.
-
x%2Bx%2B10%2B4x%2B40=92
6x%2B50=92
6x=92-50
6x=42
highlight%28highlight_green%28x=7%29%29

Now evaluate the other two expressions, for "second" and "third" numbers.
The Numbers     Expressions     Value
first            x               7
second           x+10           7+10=17
third            4(x+10)         4*17=68
SUM               92            7+17+68=24+68=92 as expected

The three numbers are 7, 17, 68.
