3m-1/5-m/7=3Solve And Check Please Its Urgent

Answer»

• SOLVING

3M - 1/5 - m/7 = 3

3m - m/7 = 3 + 1/5

( 21m - m ) / 7 = ( 15 + 1 ) / 5

20m / 7 = 16 / 5

20m x 5 = 16 x 7

100M = 112

m = 112/100

m = 1.12

• CHECKING

20m / 7 = 16 / 5

20 x 1.12 / 7 = 16 / 5

22.4/7 = 16/5

3.2 = 3.2

Hence checked
