Will Mark Brainliest!!! Which statement represents the simplified form of the given equation and correctly describes the solutio
Iteru [2.4K]

The statement 14 \neq 15 no solutions represents the simplified form of the given equation 6x + 14 = 3(2x + 5). Hence Option A is correct

<u>Solution:</u>

Given, equation is 6x + 14 = 3(2x + 5).

We have to find the correct options that represents the simplified form of the given equation and correctly describes the solution.

So, now let us simplify the given equation  

⇒6x + 14 = 3(2x + 5) ⇒ 6x + 14 = 6x + 15 ⇒ 6x – 6x + 14 = 15 ⇒ 14 ≠ 15

As L.H.S not equals with R.H.S, no value of x can satisfy the equation and there will be no solution for given equation.

Hence, option A is correct.
