Equation to find number's value: 
Number's value: n = 35
Explanation:
Let n be the unknown number for this problem.
One fifth of a number is the same as 
.
Three times the number is the same as 3n.
Twice the number plus 42 is the same as 2n + 42.
So, using the information we've gathered so far, we can create the equation that will provide us with n's value.
Equation:
We can use this equation to find n's value.
You can subtract 2n from both sides to get the equation 
, which is the same thing as the equation we were using.
Now add n and together to get 
.
After you do this, your equation should look like 
.
Now divide both sides by 
to get n's value.
n = 35
