Question

a)  \(\dfrac{5x-2}{3}=\dfrac{5-3x}{2}\)

b)  \(\dfrac{5x-2}{3}=\dfrac{5-3x}{-2}\)

Answer 1

a, \(\Rightarrow10x-4=15-9x\Leftrightarrow19x=19\Leftrightarrow x=1\)

b, \(\Rightarrow-10x+4=15-9x\Leftrightarrow x=-11\)

Answer 2

a: =>2(5x-2)=3(5-3x)

=>10x-4=15-9x

=>19x=19

hay x=1

b: =>-2(5x-2)=3(5-3x)

=>-10x+4=15-9x

=>-x=11

hay x=-11

Answer 3

a)<=>\(2\left(5x-2\right)=3\left(5-3x\right)\)

   <=>10x-4=15-9x

   <=>x=19

b)<=>-2(5x-2)=3(5-3x)

   <=>-10x+4=15-9x

   <=>x=-11

Answer 4

\(a,\dfrac{5x-2}{3}=\dfrac{5-3x}{2}\\ \Leftrightarrow2\left(5x-2\right)=3\left(5-3x\right)\\ \Leftrightarrow10x-4=15-9x\\ \Leftrightarrow10x-4-15+9x=0\\ \Leftrightarrow19x-19=0\\ \Leftrightarrow19x=19\\ \Leftrightarrow x=1\\ b,\dfrac{5x-2}{3}=\dfrac{5-3x}{-2}\\ \Leftrightarrow-2\left(5x-2\right)=3\left(5-3x\right)\\ \Leftrightarrow4-10x=15-9x\\ \Leftrightarrow15-9x-4+10x=0\\ \Leftrightarrow x+11=0\\ \Leftrightarrow x=-11\)

Answer 5

a) \(\dfrac{5x-2}{3}=\dfrac{5-3x}{2}\)

\(10x-4=15-9x\)

\(19x=19\)

\(x=1\)

b) \(\dfrac{5x-2}{3}=\dfrac{5-3x}{-2}\)

\(4-10x=15-9x\)

\(-x=11\)

\(x=-11\)
