How many solutions can be found in the linear equation? 3 (x+4) = 3x+4

A. no solution B. one solution C. two solutions D. infinite solutions

Olve equations which require undoing 1 operation1.) x - 6 = - 122.) x + 6 = - 123.) x/6 = - 124.) 6x = - 125.) - x = - 126.) 5x/6 = - 12Solve equations which require undoing 2 operations7.) 3 + 2x = - 18.) 3x + 4 (x - 1) = 2Solve equations which require undoing many operations, some on each side. 9.) 3 + 2x = 4x - 1 10.) 4x + 2 - 3x + 5 - 2 (x + 5) = (2x - 5) + (3x + 4) Infenete Solution!

3 (x + 4) = 3x + 4

3x + 12 = 3x + 4

3x - 3x = 4 - 12

0 = - 8 (incorrect ... no solution)

little tip ...

if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.

if it ends with something unequal with no variable, like 0 = - 4 or 5 = 7, then there is no solution.

if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.
