Question

x-3/3+x-4/7=2x-1/5 value of x​

Answer 1

Answer:

$\frac{x - 3}{3} + \frac{x - 4}{7} = \frac{2x - 1}{5} \\ \frac{7x - 21 + 3x - 12}{21} = \frac{2x - 1}{5} \\ 5(7x - 21 + 3x - 12) = 21(2x - 1) \\ 35x - 105 + 15x - 60 = 42x - 21 \\ 50x - 165 = 42x - 21 \\ 50x - 42x = - 21 + 165 \\ 8x = 144 \\ x = \frac{144}{8} \\ x = 18$
