Consider the equation below.

Eduardwww [97]

Answer:

The equation has no solutions .

Step-by-step explanation:

Given as :

<u>The linear equation is </u>

$\dfrac{3}{4}$ (24 -16 x) = $\dfrac{-2}{3}$ (18 x -27)

Or, $\dfrac{3}{4}$ ×24 - $\dfrac{3}{4}$ × 16 x = $\dfrac{-2}{3}$ × 18 x - $\dfrac{-2}{3}$ × 27

Or, $\dfrac{3}{4}$ ×24 - $\dfrac{3}{4}$ × 16 x = $\dfrac{-2}{3}$ × 18 x + $\dfrac{2}{3}$ × 27

Or, $\frac{3\times 24}{4}$ - $\frac{3\times 16 x}{4}$ = $\frac{-2\times 18 x}{3}$ + $\frac{2\times 27 x}{3}$

Or, 3 × 6 - 3 × 4 x = - 2 × 6 x + 2 × 9

Or, 18 - 12 x = - 12 x + 18

Or, 18 - 18 = - 12 x + 12 x

or, 0 = 0

∵ The linear equation has no variables , so the equation has no solution

Hence,The equation has no solutions . Answer
