Solve 4 (x + 1) = 4x + 4.

No solution

0

All real numbers

1

4 (x + 1) = 4x + 4

Let's start by solving the parentesis

You have to multiplt 4 for x and 1

4x + 4 = 4x + 4

Since all the terms are of the same sign but in different position (if you subtract 4x and 4 to both sides or you move known terms to the right of equal with changed sign and same for the unknown terms but to the left of thr equal) ...

0x = 0

So all real numbers ...
