Question

find the value of x. 7x- 5 /3 = 7x + 5 / 4​

Answer 1

Answer:

Step-by-step explanation:

$x * 7x - \frac{5}{3} = 7x + \frac{5}{4} \\x * 7x -7x = \frac{5}{3} + \frac{5}{4} \\x = \frac{20 + 16}{12} \\x = \frac{36}{12} \\x = 3$

Answer 2

• Answer: x ∈ ∅

Step-by-step explanation:

Hello! ʕ •ᴥ•ʔ

7x - 5/3 = 7x + 5/4 ⇒ eliminate equal terms from both sides of the equation;

⇒ -5/3 ≠ 5/4 ⇒ the relation is false for any value of x;

⇒ x ∈ ∅ → the result;
