Answer 2

Answer:

∴ The required value of $x$ in linear equation $3x+15=60$ is $15$.      

Step-by-step explanation:

In context to question asked,

• We have to find the value of $x$ in a linear equation $3x+15=60$
• To find the value of $x$, we have to use transposition method.
• The given linear equation is,

        $3x+15=60$

• Transpose $15$ to other side, we get

         ∴ $3x=60-15$

         ∴ $3x=45$

• Transpose $3$ to other side, we get

          ∴ $x=\frac{45}{3}$

          ∴ $x=15$

• ∴ The required value of $x$ in linear equation $3x+15=60$ is $15$.
