Answer 2

Let's start by simplifying the left-hand side of the equation:

3(2х+5) - 2(5х+7) = 6х + 15 - 10х - 14 = -4х + 1

And now let's simplify the right-hand side of the equation:

7(х-15) - 6 7/8 = 7х - 105 - 6 7/8 = 7х - 111 7/8

So the original equation becomes:

-4х + 1 = 7х - 111 7/8

Let's isolate the variable x on one side of the equation by adding 4x and 111 7/8 to both sides:

-4х + 4х + 1 + 111 7/8 = 7х + 4х - 111 7/8 + 111 7/8

1 + 111 7/8 = 11*8/8 + 111 7/8 = 120

Simplifying the right-hand side further:

11х = 120

Finally, we can solve for x by dividing both sides by 11:

х = 120/11

Therefore, the solution to the equation is:

х = 10 10/11 (in mixed fraction form) or х = 10.909090... (in decimal form)
