Question

2x/5+44/9=14 and 5x/3-77/9=11 solve by using cross multiplication method​

Answer 1

Step-by-step explanation:

2x/5+44/9=14 now take L.c.m of 9,5

9×2x+5×44/45=14

18x+220/45=14

do cross multiplication

18x+220=45×14

18x+220=630

18x=630-220

18x=410

x=410/18

this answer is only for 2x/5+44/9=14

5x/3-77/9=11 now take L.c.m of 3,9

3×5x-77/9=11

15x-77/9=11

now do cross multiplication

15x-77=11×9

15x-77=99

15x=99+77

15x=176

x=176/15

this answer is only for 5x/3-77/9
