Question

Find the value of x in the following equation ?
x-3/3+x-4/7=2x-1/5








​

Answer 1

Answer:(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
