Question

one-third of a number is added to 5 resulted 7 then form the equation and solve it
​

Answer 1

Answer:

6

Step-by-step explanation:

Let the no. be $x$

one-third of $x$ = $x\frac{1}{3}$

Here, $x\frac{1}{3}$ + 5 = 7

    =>  $x\frac{1}{3}$       = 7 - 5

    =>  $x$         = 2 × $\frac{3}{1}$

    =>  $x$         = 6

x = 6
