x+3/7 - 2x-5/3 = 3x-5/5 - 25
Or,
x-2x-3x= - 5/5 - 25 - 3/7 +5/3
Or!
- 4x = - 1 - 25 - 3/7 + 5/3 = (-26*21*-3*3+5*3)/21
Or,
- 4x = (-546 - 9 + 15)/21 = - 540/21 = - 180/7
Or,
x=180/28=45/7=6. 43
x= 6.43

Hope it help you!!!

You mean
x + \frac{3}{7} - 2x - \frac{5}{3} = 3x - \frac{5}{5} - 25
So, we will first find the L.C.M of the LHS and RHS.
=
 \frac{21x + 9 - 42x - 35}{21} = \frac{15x - 5 - 125}{5}
First, we will solve like terms and then we will cross multiply.
=》(-21x-26)×5=(15x-130)×21
=》-105x-130=315x-2,730
On transposing.
=》315x+105x=2,730-130
=》420x=2,600
=》x=2,600÷420
x = \frac{130}{21}
Or,
x = 6.190476190

Hope it helps.
