The first thing you would do is simplify the inside of the parenthesis to 55/6 using PEMDAS. Next all you do is multiply that by 5 to get 275/6 or 45.833 (repeating) in decimal form.

For the first picture..........

x+8 10
-----=----
2x-5 14
10(2x-5)=14(x+8)
20x-50 = 14x+112
20x-14x = 112+50
6x = 162
x= 162/6
x=27.....

x 7.5
4×X = 3×7.5
x = 22.5/4
x = 5.625....
