Chapter 2: Q20. (page 100)

Solve each equation. Check your solution.
$3 (3 m - 2) = 2 (3 m + 3)$

Short Answer

Expert verified

The solution of the given equation is $m = 4$ .

Step by step solution

Step 1. Write the given equation.

The given equation is “ $3 (3 m - 2) = 2 (3 m + 3)$ ”.

Step 2. Solve the given equation.

Solving,

$3 (3 m - 2) = 2 (3 m + 3)$ (Given equation)

$9 m - 6 = 6 m + 6$ (Distributive property)

$9 m - 6 - 6 m = 6 m + 6 - 6 m$ (Subtract $6 m$ from both sides)

$3 m - 6 = 6$ (Simplify)

$3 m - 6 + 6 = 6 + 6$ (Add 6 to both sides)

$3 m = 12$ (Simplify)

$\frac{3 m}{3} = \frac{12}{3}$ (Divide both sides by 3)

$m = 4$ (Simplify)

So, $m = 4$ is the solution of the given equation.

Step 3. Check the obtained solution.

Put $m = 4$ in the given equation $3 (3 m - 2) = 2 (3 m + 3)$ to get,

$\begin{array}{l} 3 (3 (4) - 2) = 2 (3 (4) + 3) \\ 3 (12 - 2) = 2 (12 + 3) \\ 3 (10) = 2 (15) \\ 30 = 30 \end{array}$

Since the value obtained on the left-hand side and right-hand side are equal, the obtained value is indeed a solution of the given equation.
