Answer:
x=7/4
Step-by-step explanation:
4x=-7=4x/-4=-7/-4= x=7/4
I find the problem confusing because it forces a certain sequence of thought process, and I find I get way beyond these questions and answers rather quickly. I would start with the equation of part B, having already recognized the conversions of percent to decimal and the need to make the acid quantities add up. Doing the problem a different way gets you to the answer in part C without any of these "steps," so going back and trying to fill in the "steps" seems awkward, at best.

The preferred technique is to factor each number then multiply all common factors together to find the greatest common factor.
Explanation:
First factor 20 down to its prime factors.
<span>2×2×5</span>
Second factor 30 down to its prime factors
<span>2×3×5</span>
The common factors are 2 and 5.
The greatest common factor is <span>2×5=10</span>
There are shortcuts that often work however
20 can be easily factored into <span>2×10</span> while
30 can be easily factored into <span>3×10</span>
10 can then be easily be seen as the greatest common factor.
