Given : (x + 3)/7 - (2x-5)/3 = (3x - 5)/5 - 25
To Find : x
Verify
Solution:
(x + 3)/7 - (2x-5)/3 = (3x - 5)/5 - 25
Multiply both sides by 5 * 7 * 3
=> 15(x + 3) - 35(2x - 5) = 21(3x - 5) - 25*105
=> 15x + 45 - 70x + 175 = 63x - 105 - 25*105
=> -55x + 220 = 63x - 105*26
=> 118x = 105*26 + 220
=> 118x = 2950
=> x = 25
LHS =
(x + 3)/7 - (2x-5)/3
= (25 + 3)/7 - ( 50 - 5)/3
= 4 - 15
= - 11
RHS
= (3x - 5)/5 - 25
= (75 - 5)/5 - 25
= 14 - 25
= - 11
LHS = RHS = - 11
