Step-by-step explanation:

for x

3x + y = -1

for y

3x + y = -1

3x = -y -1

divide by 3

x = -1/2y - 1/3

Alright! So to solve these questions, you need to find out the difference. You can use ratios to solve this. For example, question #25:

A class had 30 pupils at the beginning of this school term, but now has 5 more pupils. What is the percent of increase?

The question is basically asking how much 5 is in ratio to 30. So just divide 5 (the given amount) by 30 (the total amount). The answer is 0.16, or 16%
