-45(3x-17)=3
-135x-765=3
-135x=3+765
-135x=768
x=\(\dfrac{-768}{135}\)
x=-5,7
vậy x= -5,7
-45. (3x - 17 )
-135x - 765 = 3
-135x = 765 + 3
-135x = 768
x =-768/135
x = 5,7 like nhé
\(\text{-45(3x-17)=3}\Leftrightarrow3x-17=\dfrac{-1}{15}\)
\(\Leftrightarrow3x=\dfrac{254}{15}\)
\(\Leftrightarrow x=\dfrac{254}{45}\)
\(\text{Vậy }x=\dfrac{254}{45}\)
