Question

Solve (x - 3)/4 + (x - 1)/5 - (x - 2)/3 = 1

Answer 1

Answer:

(x-3)/4 + (x-1)/5 - (x-2)/3 = 1

or, 15(x-3)/60 + 12(x-1)/60 - 20(x-2)/60 = 1

or, (15x-45)/60 + (12x-12)/60 - (20x-40)/60 = 1

or, {(15x-45)+(12x-12)-(20x-40)}/60 = 1

or, {15x-45+12x-12-20x+40}/60 = 1

or, {7x-17}/60 = 1

or, 7x-17 = 60

or, 7x = 60+17

or, 7x = 77

or, x = 77/7

or, x = 11
