Answer 2

To solve the equation, first, distribute the numbers outside the parentheses:

3(x - 5) - 7(x + 1)

= 3x - 15 - 7x - 7

Now, combine like terms:

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

= -4x - 22

So the simplified equation is:

-4x - 22 = 0

To isolate the variable x, add 22 to both sides:

-4x - 22 + 22 = 0 + 22

-4x = 22

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

x = 22 / (-4)

x = -5.5

So, the value of x that satisfies the equation is -5.5.
