Question

Giá trị a thoã mãn

\(\frac{a}{3}=\frac{2a+2}{5}\)

Answer 1

\(\frac{a}{3}=\frac{2a+2}{5}\)

\(\Rightarrow3\left(2a+2\right)=5a\)

\(\Rightarrow6a+6=5a\)

\(\Rightarrow a=6\)

Vậy a = 6

Answer 2

Ta có: \(\frac{a}{3}=\frac{2a+2}{5}\)

=> 5a=3(2a+2)

=> 5a=6a+6

=> 6=5a-6a

=> 6=-a

=> a=-6

Vậy a=-6

 

\(\frac{a}{3}=\frac{2a+2}{5}\)a

 

Answer 3

\(\frac{a}{3}=\frac{2a+2}{5}\)

\(\Rightarrow5a=6a+6\)

\(5a-6a=6\)

\(-a=6\)

\(\Rightarrow a=-6\)

Answer 4

ta có a/3 = 2a + 2 / 5

=> 5a = 3(2a + 2)

=> 5a = 6a + 6

=> 5a - 6a = 6

=> -a = 6

=> a= -6

Vậy a = -6
