Chapter 2: Q14. (page 100)

Solve each equation. Check your solution.
$\frac{b - 4}{6} = \frac{b}{2}$

Short Answer

Expert verified

The solution of the given equation is $b = - 2$ .

Step by step solution

Step 1. Write the given equation.

The given equation is “ $\frac{b - 4}{6} = \frac{b}{2}$ ”.

Step 2. Solve the given equation.

Solving,

$\frac{b - 4}{6} = \frac{b}{2}$ (Given equation)

$2 (b - 4) = 6 b$ (Cross-multiply)

$2 b - 8 = 6 b$ (Distributive property)

$2 b - 8 - 2 b = 6 b - 2 b$ (Subtract $2 b$ from both sides)

$- 8 = 4 b$ (Simplify)

$\frac{- 8}{4} = \frac{4 b}{4}$ (Divide both sides by 4)

$- 2 = b$ (Simplify)

$b = - 2$ (Write the variable on the left-hand side)

So, $b = - 2$ is the solution of the given equation.

Step 3. Check the obtained solution.

Put $b = - 2$ in the given equation $\frac{b - 4}{6} = \frac{b}{2}$ to get,

$\begin{array}{l} \frac{- 2 - 4}{6} = \frac{- 2}{2} \\ \frac{- 6}{6} = - 1 \\ - 1 = - 1 \end{array}$

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.
