Answer:
of Diana's clothes are black or white
Step-by-step explanation:
In order to find the total amount of Diana's clothes that are black or white, you need to add the fractional amount of clothes that are white (1/6) and the fractional amount that are black (7/12). But, when you add fractions they need to have the same denominator, so you need to find the least common multiple of both denominators, in this case '12':

So, 
Now, simplify: 
Answer: 105 = WXZ

Hi there! :)
<u>Infinite solutions.</u>
2x + 8 = 2(x + 4)
Distribute the 2 with the terms inside of the parenthesis:
2x + 8 = 2(x) + 2(4)
Simplify:
2x + 8 = 2x + 8
Subtract 2x from both sides:
2x - 2x + 8 = 2x - 2x + 8
0 + 8 = 8
Subtract 8 from both sides:
0 + 8 - 8 = 8 - 8
0 = 0
Therefore, there are infinite solutions.
