Ответ:To solve the equation:
(6x + 7)/7 - (5x - 3)/8 = 3
We can start by getting rid of the denominators by finding a common denominator of 56.
Multiplying both sides by 56, we get:
8(6x + 7) - 7(5x - 3) = 168
Expanding the brackets, we get:
48x + 56 - 35x + 21 = 168
Combining like terms, we get:
13x + 77 = 168
Subtracting 77 from both sides, we get:
13x = 91
Dividing both sides by 13, we get:
x = 7
Therefore, the solution to the equation is x = 7.
