It is not clear which of the two xs that appear in the expression you refer to; nor is there an inequality or inequality sign in the first part of the question.
12 divided by 3 equals 4. Then, 4 times 3 equals 12. Finally, 4 plus 12 equals 16.

In 6x + 4 = 12, x = 4/3
1/4 + 1/3 = 3/12 + 4/12 (12 is the least common multiple of 3 and 4) = 7/12
(x+3)(x+4)=x2+7x+12
12 divided by 3 equals 4. Then, 4 times 3 equals 12. Finally, 4 plus 12 equals 16.

1 1/2 plus 4 2/3 equals 5 3/5.
It equals 8x+12
In 6x + 4 = 12, x = 4/3
1/4 + 1/3 = 3/12 + 4/12 (12 is the least common multiple of 3 and 4) = 7/12
(x+3)(x+4)=x2+7x+12
12 divided by 4 plus 2 times 3 = 9
3x+8 = 12 3x = 4 x = 4/3
(x+3)(x+4) = x2+7x+12
3 plus 1 plus 4 equals 8
4 plus 3 equals 7
