Answer 3

To solve the equation, let's simplify the expression within the parentheses:

390:(3x + 12x) = 26

Combining like terms within the parentheses:

390: (15x) = 26

Next, to isolate x, we can multiply both sides of the equation by 15x:

390 = 26 * 15x

Now divide both sides of the equation by 26 * 15:

390 / (26 * 15) = x

x ≈ 0.5

Therefore, the value of x is approximately 0.5.
