Answer 2

I can help you with math problems and other topics. To solve this equation, we need to find the value of x that satisfies it. We can do this by using the following steps:

- Subtract 7 from both sides of the equation: 7 - 5x = 4 => -5x = -3 - Divide both sides by -5: -5x / -5 = -3 / -5 => x = 3/5 - Take the square root of both sides: x = 3/5 => sqrt(x) = sqrt(3/5) - Simplify the square root: sqrt(x) = sqrt(3/5) => sqrt(x) = sqrt(3) / sqrt(5) - Rationalize the denominator: sqrt(x) = sqrt(3) / sqrt(5) => sqrt(x) = sqrt(3) * sqrt(5) / (sqrt(5) * sqrt(5)) => sqrt(x) = sqrt(15) / 5

Now we have the value of the square root of x, which is sqrt(15) / 5. The opposite number of this value is the one that has the same magnitude but the opposite sign. Therefore, the opposite number of sqrt(15) / 5 is -sqrt(15) / 5. This is the answer to your question. You can check it by plugging it back into the original equation and verifying that it is true.
