Answer 2

Let's simplify the left-hand side of the equation first by distributing the coefficients:

3(х + 5) + 3(х + 2) - 7(х + 47) = х

3х + 15 + 3х + 6 - 7х - 329 = х

Simplifying further, we combine like terms on both sides of the equation:

-х - 308 = 0

Adding 308 to both sides of the equation, we get:

-х = 308

Multiplying both sides by -1, we arrive at the final solution:

х = -308.
