Question
Simplify: `(5 ("x" - 4))/3 + (2(5x - 3))/5 + (6(x - 4))/7`
Sum
Solution
`(5 ("x" - 4))/3 + (2(5x - 3))/5 + (6(x - 4))/7`
`=(175("x - 4") + 42("x" - 3) +90("x" - 4))/105` ...(LCM of 3,5,7 = 105)
`= (175"x" - 700 + 210"x" - 126 + 90"x" - 360)/105`
`= (175"x" + 210"x" + 90"x" - 700 - 126 - 360)/105`
`= (475"x" - 1186)/105`
