Given, 3x+55−x−23=5x−76
⟹ 3(3x+5)−5(x−2)5×3=5x−76 …[Cross-multiplying the denominators on the LHS]
⟹ 9x+15−5x+105×3=5x−76 ...[By Distribution Law]
⟹ 4x+255=5x−72 ...[Multiplying 3 on both sides and simplifying]
⟹ (4x+25)2=(5x−7)5 …[Cross-multiplying the denominators]
⟹ 8x+50=25x−35 ...[By Distribution Law]
⟹ 35+50=25x−8x ...[Transposing x terms to one side]
⟹ 17x=85 ...[On simplifying]
⟹ x=8517 ...[Dividing 175 on both sides]
⟹ x=5.
