Question

2x-70%x=-1.7 ai giúp mình với 

Answer 1

\(2x-70\%x=-1,7\)

\(\Rightarrow2x-0,7x=-1,7\)

\(\Rightarrow\left(2-0,7\right)x=-1,7\)

\(\Rightarrow1,3x=-1,7\)

\(\Rightarrow x=\frac{-17}{13}\)

Answer 2

2x - 7/10x = -17/10

x.(2-7/10) = -17/10

x.13/10 = -17/10

x=-17/10 : 13/10

x=-17/13

Answer 3

2x - 7/10x = -17/10

x.(2-7/10) = -17/10

x.13/10 = -17/10

x=-17/10 : 13/10

x=-17/13
