Chapter 2: Q 2.3 (page 100)

Solve: $2 (m - 4) + 3 = - 1$ .

Short Answer

Expert verified

The solution of the linear equation is $m = 2$ .

Step by step solution

Step 1. Given information.

Solve the below linear equation, $2 (m - 4) + 3 = - 1$ .

Step 2. Use the distributive property so solve the linear equation.

$2 (m - 4) + 3 = - 1 2 m - 2 \cdot 4 + 3 = - 1 2 m - 8 + 3 = - 1 2 m - 5 = - 1 2 m - 5 + 5 = - 1 + 5 2 m = 4 m = \frac{4}{2} m = 2$

Step 3. Check the solution.

Put $m = 2$ into the equation.

$2 (m - 4) + 3 = - 1 2 (2 - 4) + 3 = - 1 4 - 8 + 3 = - 1 7 - 8 = - 1 - 1 = - 1$

Hence, the solution is correct.

Step 4. Conclusion.

The solution of the given linear equation is $m = 2$ .
