To solve the equation х/4 + х/3 = х/6 + 5, first find a common denominator. In this case, the smallest common denominator is 12.

Multiplying each term by 12 to get rid of the fractions:

3х + 4х = 2х + 30
7х = 2х + 30
Subtract 2х from both sides:

5х = 30
Divide by 5:

х = 6

Therefore, the solution to the equation is х = 6.

To solve the equation 2х/3 - 4х/5 = х/15 + 13х/8 - х/6, find a common denominator of 120 (the smallest common multiple of 3, 5, 15, 8, and 6).

Multiplying each term by 120:

80х - 96х = 8х + 195x - 20х
Simplify:

-16х = 183x - 20x
Combine like terms:

-16х = 163x
Divide by -16:

x = -163/16

Therefore, the solution to the equation is х = -163/16.

To solve the equation х/12 - 1 = 0, first move the constant to the other side:

х/12 = 1
Multiply by 12 to isolate x:

х = 12

So, the solution to the equation is x = 12.
