-4x-22

Объяснение:

=3x-15-7x-7= - 4x-22

Answer 3

To solve the equation 3(x - 5) - 7(x + 1) = 0 for x, you can follow these steps:

1. Distribute the constants outside the parentheses to the terms inside the parentheses:

   3x - 15 - 7x - 7 = 0

2. Combine like terms by adding or subtracting them:

   (3x - 7x) + (-15 - 7) = 0

   -4x - 22 = 0

3. Add 22 to both sides of the equation to isolate the variable term:

   -4x = 22

4. Finally, divide both sides by -4 to solve for x:

   x = 22 / (-4)

   x = -11/2

So, the solution to the equation is:

x = -11/2
