35 students   -    25 % ( or 1/4 of the all students )
35 * 4 = 140
140 - 35 = 105

100 % - 75 % = 25 %

25 % = 1/4 of 100 %
75 % = 3/4 of 100 %

35 students = 25 % 

35 * 3 = 105

If 35 students of the school did not like skating, the number of students who liked skating was 105.

Answer:

6. The number is -5

7. The two numbers are 10 and 11

Step-by-step explanation:

Question six can be re-worded to create the following expression:

-2=\frac{4x+10}{5}

Solve for x to find the number:

-2=\frac{4x+10}{5}\\-10=4x+10\\-20=4x\\\frac{-20}{4} = x\\-5 = x

Question seven can be solved by first listing the constraints (assuming x is smaller than y):

  1. x and y are less than 20
  2. x + 1 = y
  3. 3x - 8 = 2y

To get the numbers, we can create a system of linear equations. First, solve for y in each expression:

y = x+1

2y = 3x-8\\y = \frac{3}{2}x - 4

Solve for x:

x+ 1 = \frac{3}{2}x - 4\\x + 5 = \frac{3}{2}x\\5 = \frac{3}{2}x - x\\5 = \frac{1}{2}x\\10 = x

Solve for y:

y = x + 1\\y = 10 + 1\\y= 11
