(5X - 3) +( 7x - 4 )= 8 - (15 - 11x)

To solve the given equation, we will simplify each side separately and then combine like terms.

Starting with the left side of the equation:

(5x - 3) + (7x - 4)

Applying the parentheses, we can simplify the expression inside each set of parentheses:

5x - 3 + 7x - 4

Now we combine like terms:

12x - 7

Now, moving on to the right side of the equation:

8 - (15 - 11x)

We can simplify the expression inside the parentheses:

8 - 15 + 11x

Combine like terms:

-7 + 11x

Now, the given equation becomes:

12x - 7 = -7 + 11x

To solve for x, we move all x terms to one side and all constant terms to the other side.

Subtracting 11x from both sides:

12x - 11x - 7 = -7 - 11x + 11x

Simplifying:

x - 7 = -7

Adding 7 to both sides:

x - 7 + 7 = -7 + 7

Simplifying:

x = 0

Therefore, the solution to the given equation is x = 0.
