\(\frac{x+1}{x-2}=\frac{3}{4}\)
\(\Rightarrow4x+4=3x-6\)
\(x=-10\)
---------------------------------------------------
\(\frac{x-1}{x+1}=\frac{x}{x-2}\)
\(\Rightarrow\left(x-1\right)\left(x-2\right)=x\left(x+1\right)\)
\(x^2-x-2x+2=x^2+x\)
\(4x=2\)
\(x=\frac{1}{2}\)
\(\frac{x+1}{x-2}=\frac{3}{4}\)
\(\Leftrightarrow\left(x+1\right).4=\left(x-2\right).3\)
\(\Leftrightarrow4x+4=3x-6\)
\(\Leftrightarrow4x-3x=-6-4\)
\(\Leftrightarrow x=-10\)
a) 4(x+1) - 3(x-2) <=> 4x+4-3x+6 <=> 4x-3x = 6-4 <=> x=2 b) (x-1)(x-2) = x(x+1) <=> x^2 -2x -x +2 = x^2 +x <=> -4x=-2 <=> x=1/2
