Chapter 2: Q.33. (page 112)

Classify the below equation as a conditional equation, an identity, or a contradiction, and then state the solution.
$18 (5 j - 1) + 29 = 47$

Short Answer

Expert verified

The equation is a conditional equation and the solution of this equation is $j = \frac{2}{5}$ .

Step by step solution

Step 1. Given information.

The given equation is $18 (5 j - 1) + 29 = 47$ .

Step 2. Apply the distributive property to simplify the equation.

$18 \times 5 j - 18 + 29 = 47 90 j - 18 + 29 = 47 90 j + 11 = 47$

Step 3. Collect all constant terms on one side of the equation and then simplify.

Subtract $11$ from each side.

$90 j + 11 - 11 = 47 - 11 90 j = 36$

Divide each side by $90$ .

$\frac{90 j}{90} = \frac{36}{90} j = \frac{2}{5}$

From the above result, we can say that the given equation is true only for $j = \frac{2}{5}$ .

So, the equation is a conditional equation.

Hence, the solution of the given equation is $j = \frac{2}{5}$ .
