[urgent] how to calculate the division of one variable linear equation

(x-48) × 2 / 3 - (x + 15) × 5 / 4 = 14
(x-48)×3/2-(x+15)×4/5=14
De denominator: 15 (x-48) - 8 (x + 15) = 140
Remove brackets: 15x-720-8x-120 = 140
Transfer: 15x-8x = 140 + 720 + 120
Merge similar items: 7x = 980
The coefficient is 1: x = 140
