Question

Find the value of x in each of the following.
x+5/9 -(-7)/12=13/36
​

Answer 1

= X+5 /9 - (-7)/12 =13/36

X+5/9 -7/12 =13/36

Now take a lcm 9, 12 is

X+5/9 × 12/12 -7/12 ×9/9=13/36

12x+60/108 -63/108 =13/36

12x+60-63/108 =13/36

12X+(-3)/108 =13/36

12x-3/108 =13/36

by cross multiplication

12X-3(36)= 1404

432x-108 =1404

432x= 1404+108

432x = 1512

x =1512/432

x= 3.5
