Question

x/9 - 43 = 1000
x/7 - 5 = 0
5/2x + 40 = 500

Answer 1

x/9 - 43 = 1000

x/9 = 1000 + 43

x = 1043

x = 1043 * 9

x = 9387
----------------------

x/7 - 5 = 0

x/7 = 0 + 5

x/7 = 5

x = 5 * 7

x = 35
----------------------------

5/2x + 40 = 500

(5x)/2 + 40 = 500

(5x + 80)/2 = 500

5x + 80 = 1000

5x = 1000 - 80

5x = 920

x = 920/5

x = 184
