## Elementary Geometry for College Students (6th Edition)

We multiply both sides by 2, 3 and 4 at the same time: $\frac{x}{2}\times 2\times 3\times 4 + \frac{x}{3}\times 2\times 3\times 4 + \frac{x}{4}\times 2\times 3\times 4 = 26\times 2\times 3\times 4$ $12x + 8x + 6x = 624$ $26x = 624$ We divide by 26: $x= 624\div 26 = 24$
