(x-3)/3 + (x-4)/7 = (2x-1) /5
lcm of 3,7 is 21
(7(x-3) + 3(x-4) )/21 = (2x-1)/5
(7x - 21 + 3x - 12 )/21 = (2x-1)/5
(10x -33)5 = 21(2x-1)
50x - 165 = 42x - 21
50x - 42x = 165 - 21
8x = 144
x = 144/8 = 18
so....x = 18
lcm of 3,7 is 21
(7(x-3) + 3(x-4) )/21 = (2x-1)/5
(7x - 21 + 3x - 12 )/21 = (2x-1)/5
(10x -33)5 = 21(2x-1)
50x - 165 = 42x - 21
50x - 42x = 165 - 21
8x = 144
x = 144/8 = 18
so....x = 18
wrong answer
if you subtract 42 from 50 then you get 8
yes
