Solve for x: -3(x + 3) = -3(x + 1) - 5.
6, -6, All real numbers, No solution

Solution:

Any number that can be found in the real world is a real number.

We find numbers everywhere around us.

Natural numbers are used for counting objects, rational numbers are used for representing fractions, irrational numbers are used for calculating the square root of a number, integers for measuring temperature, and so on.

Given,

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

-3x - 9 = - 3x - 3 - 5

By transposing we get

-3x + 3x = - 3 - 5 + 9

0 = 1

No Solution

Therefore, by solving we find that there is no solution.
