Short Answer

Expert verified

Ans: $\sqrt{2 x - 5} = \sqrt{5 x + 3} \Rightarrow x = - \frac{8}{3}$

Step by step solution

Step 1. Given information.

given, $\sqrt{2 x - 5} = \sqrt{5 x + 3}$

Step 2. Square both sides of the equation.

$\sqrt{2 x - 5} = \sqrt{5 x + 3} \Rightarrow {(\sqrt{2 x - 5})}^{2} = {(\sqrt{5 x + 3})}^{2} \Rightarrow 2 x - 5 = 5 x + 3$

Step 3. Simplify, then the new equation.

$2 x - 5 = 5 x + 3 \Rightarrow 3 x = - 8 \Rightarrow x = - \frac{8}{3}$

Therefore, the value of $x = - \frac{8}{3}$
