SOLUTION: Solve. –6(x + 3) – 10 = 3(–2x – 5) – 13 Here is what I ahve -6(3 + x) + -10 = 3(-2x + -5) + -13 (3 * -6 + x * -6) + -10 = 3(-2x + -5) + -13 (-18 + -6x) + -10 = 3(-2x + -5)

Distribute
add 28 to both sides
Divide by negative one


This means that for this particular equation, x can be ANY value.
The domain is (-infinity, infinity)
Any X value will satisfy the equation above ^_^

For example, x can equal (any number, even) one:
-6(1+3)-10=3(-2(1)-5)-13
-6(4)-10=3(-7)-13
-24-10=-21-13
-34=-34  Thus the equation is satisfied.

Another example:  X=0 (note please that all values of x will satisfy this equation)
-6(0+3)-10=3(-2(0)-5)-13
-6(3)-10=3(-5)-13
-28=-28
