Question

Tìm X a) x +3/4=4/3 B)7/12+x=3/2

Answer 1

`(a):`

`x+(3)/(4)=(4)/(3)`

`x=(4)/(3)-(3)/(4)=(16)/(12)-(9)/(12)`

`x=(7)/(12)`

`(b):`

`(7)/(12)+x=(3)/(2)`

`x=(3)/(2)-(7)/(12)=(18)/(12)-(7)/(12)`

`x=(11)/(12)`

Answer 2

a: x=4/3-3/4=16/12-9/12=7/12

b: x=3/2-7/12=11/12

Answer 3

a) \(x+\dfrac{3}{4}=\dfrac{4}{3}\)

\(x=\dfrac{4}{3}-\dfrac{3}{4}\)

\(x=\dfrac{7}{12}\)

b) \(\dfrac{7}{12}+x=\dfrac{3}{2}\)

\(x=\dfrac{3}{2}-\dfrac{7}{12}\)

\(x=\dfrac{11}{12}\)

Answer 4

`x +3/4=4/3`

`=>x=4/3 - 3/4`

`=>x= 16/12 - 9/12`

`=>x= 5/12`

`--------`

`7/12 + x= 3/2`

`=>x= 3/2-7/12`

`=>x= 18/12-7/12`

`=>x=11/12`

Answer 5

a,\(x+\dfrac{3}{4}=\dfrac{4}{3}\)

=>\(x=\dfrac{4}{3}-\dfrac{3}{4}\)

=>\(x=\dfrac{7}{12}\)

b,\(\dfrac{7}{12}+x=\dfrac{3}{2}\)

=>\(x=\dfrac{3}{2}-\dfrac{7}{12}\)

=>\(x=\dfrac{11}{12}\)
