Question

3x-2/10-x+3/7+4x-7/3=x-1

Answer 1

{(63x-42-30x-90+280x-490)}/210 = x-1
(because 10,7,3 is 210)
(313x-622)/210=x-1
313x-622= 210x-210
313x-210x= 622-210
103x= 412
x= 4

Answer 2

Hello Friend

Here is your answer

First we take like term in one side and solve it

$3x - \frac{2}{10} - x + \frac{3}{7} + 4x - \frac{7}{3} = x - 1 \\ \\ 3x + 4x - x - x = - 1 - \frac{3}{7} + \frac{7}{3} + \frac{2}{10} \\ \\ 7x - 2x = - ( \frac{7 + 3}{7} ) + ( \frac{70 + 6}{30} ) \\ \\ 5x = - \frac{10}{7} + \frac{76}{30} \\ \\ x = \frac{ - 300 + 532}{210} \\ \\ x = \frac{ - 232}{210} \\ \\ x = \frac{ - 116}{105}$
Hope it helps you
