Question

X/10 + (x+1)/17 + (x+2)/26 = 10 
 

Answer 1

The equation is x /10 + (x + 1)/17 + (x + 2)/ 26 = 10.

LCM of 10, 17, and 26 is 2210

⇒[x(221) + 130(x + 1) + 85(x + 2)] / 2210 = 10

⇒x(221) + 130(x + 1) + 85(x + 2) = 22100

⇒221x + 130x + 130 + 85x + 170= 22100

⇒436x + 300 = 22100

⇒436x  = 22100 - 300 

⇒436x  = 21800

⇒x = 21800 / 436

x = 50

The solution is x = 50
