(3X + 10x) умножить на 8 = 312

To solve the equation (3X + 10x) * 8 = 312, we need to simplify both sides of the equation.

On the left side, we multiply 8 by the expression (3X + 10x):

8 * (3X + 10x) = 24X + 80x

Now our equation becomes:

24X + 80x = 312

To solve for X, we need to combine like terms. Since the variables X and x are not like terms, we cannot combine them.

Therefore, we cannot solve for X using this equation. Please provide more information or check if there was a mistake.
