Question

tìm x

3 và 1/3 . x + 11 và 3/4 = ( - 13, 25 ) 

Answer 1

10/3.x+47/4=-53/4

10/3.x=-53/4-47/4

10/3.x=-25

x=-25:10/3

x=-15/2

Answer 2

\(3\dfrac{1}{3}.x+11\dfrac{3}{4}=\left(-13,25\right)\) 

  \(\dfrac{10}{3}.x+\dfrac{47}{4}=\dfrac{-53}{4}\) 

           \(\dfrac{10}{3}.x=\dfrac{-53}{4}-\dfrac{47}{4}\) 

           \(\dfrac{10}{3}.x=-25\) 

                  \(x=-25:\dfrac{10}{3}\) 

                  \(x=\dfrac{-15}{2}\)
