Question

Answer 1

`-2/3 x = 4/15`

`=> x= 4/15 : (-2/3)`

`=>x= 4/15 xx (-3/2)`

`=>x= -12/30`

`=>x= -2/5`

`----------`

`-7/19 x = -13/24`

`=>x=  -13/24:( -7/19)`

`=>x= -13/24 xx (-19/7)`

`=>x= 247/168`

`--------`

`-2/5 + 5/6 x = -4/15`

`=>  5/6 x = -4/15-(-2/5)`

`=>  5/6 x =  -4/15+2/5`

`=>  5/6 x =2/15`

`=>x= 2/15 : 5/6`

`=>x= 2/15 xx 6/5`

`=>x= 4/25`

`----------`

`2/3 + 7/4 : x= 5/6`

`=>  7/4 : x= 5/6-2/3`

`=> 7/4 : x= 5/6-4/6`

`=> 7/4 : x=1/6`

`=>x= 7/4 : 1/6`

`=>x= 7/4 xx 6`

`=>x= 42/4=21/2`
