Chapter 2: Q.40. (page 112)

Classify the below equation as a conditional equation, an identity, or a contradiction, and then state the solution.
$60 (2 x - 1) = 15 (8 x + 5)$

Short Answer

Expert verified

The equation is a contradiction and the equation has no solution.

Step by step solution

Step 1. Given information.

The given equation is $60 (2 x - 1) = 15 (8 x + 5)$ .

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

$60 \times 2 x - 60 = 15 \times 8 x + 15 \times 5 120 x - 60 = 120 x + 75$

Step 3. Collect all variables terms on one side of the equation.

Subtract $120 x$ from each side.

$120 x - 60 - 120 x = 120 x + 75 - 120 x - 60 = 75 (f a l s e)$

This equation is false for all values of variable.

So, the equation is a contradiction.

Hence, the equation has no solution.
