Question

x x 2/3 -1/5 = 1 12/15

Answer 1

`x xx 2/3 -1/5 = 1 12/15`

`=> x xx 2/3 -1/5 =(1xx15+12)/15`

`=> x xx 2/3 -1/5 = 27/15`

`=> x xx 2/3= 27/15 +1/5`

`=> x xx 2/3=2`

`=>x=2 : 2/3`

`=> x= 2 xx 3/2`

`=> x = 6/2`

`=>x= 3`

vậy `x=3`

Answer 2

\(x\times\dfrac{2}{3}-\dfrac{1}{5}=1\dfrac{12}{15}\\ =>x\times\dfrac{2}{3}=\dfrac{9}{5}+\dfrac{1}{5}\\ =>x\times\dfrac{2}{3}=2\\ =>x=2:\dfrac{2}{3}\\ =>x=3\)
