3. Give a property of real numbers (associative, commutative, or distributive) or a property of equality
(addition or multiplication) that justifies each step in the following equation:
3x+1+ 2x - 7= x+22
(1) 3x + 2x +1-7 = x+
(2) x(3+2) - 6 = x+22
5x-6=X+22
(3) 5x-6+6 = x+22+
5x = x+28
(4) 5x - x = x + 28
(5) x(5-1) = 28
4x=28
(6) 34x=-=-28
