Question

x/2 + x+x/3 + x+x+x/4 =5 3/4

Answer 1

`x/2+x+x/3+x+x+x/4=5 3/4`

`x xx(1/2+1+1/3+1+1+1/4)=23/4`

`x xx49/12=23/4`

`x=23/4:49/12`

`x=23/4xx12/49=69/49`

Answer 2

`x/2 + x + 2/3 + x + x + x/4 = 5 3/4`

`=> x xx 1/2 + x xx 1 + x xx 1/3 + x xx 1 + x xx 1 + x xx 1/4 = 23/4`

`=> x xx (1/2 + 1 + 1/3 + 1 + 1 + 1/4) = 23/4`

`=> x xx 37/12 = 23/4`

`=> x                = 23/4 : 37/12`

`=> x               = 69/49`
