Can you tell me a quick way to solve this problem 2/7m-1/7=3/14

2/7m-1/7=3/14

make the denominators equal and to this just multiply the denominators of the first two equations by 2 but you have to multiply the numerators too and by the same value

4/14m - 2/14 = 3/14

with the denominators equal, you can delete them

4m-2=3

4m=3+2

4m=5

m=5/4
