• Let , number be $x$ .
• Then , according to question we are given that $3$ times a number increased by $7$ is $25$. We write, given condition as :  
• $3x + 7 = 25$  

        $3x + 7 = 25 \\3x = 25 - 7 \\x = \frac{18}{3} \\x = 6$

Hence , value of $x$ is $6$ .

       

Answer 2

Given: 3 times a number increased by 7 is 25.

We have to find the number.

We are solving in the following way:

Let assume the number be '$x$'.

From the given statement we can write:

$3x+7=25$

Solving the above equation further we get,

$\begin{array}{l}\Rightarrow 3 x+7=25 \\\\\Rightarrow 3 x=25-7 \\\\\Rightarrow x=\frac{18}{3} \\\\\Rightarrow x=6\end{array}$

Hence, the number will be$6$.
