Chapter 1: Q22. (page 48)

Simplify the expression.
$2 m + 7 n - 6 m - 5 n$

Short Answer

Expert verified

The simplification of the equation is $2 (n - 2 m)$ .

Step by step solution

Step 1- Consider the expression.

Consider the expression $2 m + 7 n - 6 m - 5 n$ .

Step 2- Step description.

Simplify the equation as follows:

\begin{array}{l} 2 m + 7 n - 6 m - 5 n \\ 2 m - 6 m + 7 n - 5 n \\ - 4 m + 2 n \end{array}

Step 3- Step description.

Take out from the equation (as it is common from both the terms) obtained as follows:

$\begin{array}{l} - 4 m + 2 n \\ 2 (- 2 m + n) \\ 2 (n - 2 m) \end{array}$

Therefore, the equation is $2 (n - 2 m)$ .
