(3X + 10x) умножить на 8 = 312

To solve the equation (3X + 10x) * 8 = 312, first simplify the equation by distributing the 8 to both terms inside the parentheses:

3X * 8 + 10x * 8 = 312

24X + 80x = 312

Then combine like terms:

104x + 24X = 312

Now, combine the X terms:

(104 + 24)X = 312

128X = 312

To solve for X, divide both sides of the equation by 128:

X = 312/128

Simplifying the fraction:

X = 2.4375
