Chapter 1: Q61. (page 32)

Solve the equation and check the solution.
$3 x + 6 = 22$

Short Answer

Expert verified

The solution is $x = \frac{16}{3}$ .

Step by step solution

Step 1- Consider the equation.

Consider the equation $3 x + 6 = 22$ .

Subtract 22 from both sides of the equation.

Step 2- Step description.

$\begin{matrix} 3 x + 6 - 22 = 0 \\ 3 x - 16 = 0 \end{matrix}$

Step 3- Step description.

Add 16 on both sides of the equation as follows:

$\begin{matrix} 3 x - 16 = 0 \\ 3 x - 16 + 16 = 16 \\ 3 x = 16 \end{matrix}$

Divide both sides of the equation by 3.

$\begin{array}{l} 3 x = 16 \\ x = \frac{16}{3} \end{array}$

Therefore, the solution is $x = \frac{16}{3}$ .

Step 4- Verify the solution.

Substitute $x = \frac{16}{3}$ in the equation and simplify as follows:

$\begin{matrix} 3 x + 6 = 22 \\ 3 (\frac{16}{3}) + 6 = 22 \\ 16 + 6 = 22 \\ 22 = 22 \end{matrix}$

Since the left-hand side of the equation is equal to the right-hand side of the equation, therefore, the solution is $x = \frac{16}{3}$ .
