Question

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

Answer 1

• 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

Answer 2

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

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

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

20m/7=16/5

20m×5=16×7

100m=112

m=112/100

m=1.12
