Answer:

see below

Step-by-step explanation:

13.  (8-x)/2  = (2x+2)/5

Using cross products

5(8-x) = 2(2x+2)

40 -5x = 4x+4

Add 5x to each side

40-5x+5x = 4x+5x+4

40 = 9x+4

Subtract 4 from each side

40 -4 = 9x

36 =9x

Divide by 9

36/9 =9x/9

4 =x

14.(x+2)/7 = (3x+6)/5

Again using cross products

5(x+2) = 7(3x+6)

5x+10 = 21x+42

Subtract 5x from each side

10 = 21x-5x +42

10 =16x+42

Subtract 42 from each side

-32 = 16x

Divide by 16

-2 =x

15.(1-x)/2 = (3-x)/3

Again using cross products

3(1-x) = 2(3-x)

3 -3x = 6 -2x

Add 3x to each side

3 = 6-2x+3x

3 = 6+x

Subtract 6 from each side

3-6 =x

-3 =x
