1)\(y=3x+2\)
\(x=\frac{y-2}{3}\)
2)\(y=4x^2-3\)
\(x=\sqrt\frac{y+3}{4}\)
3)\(3x^2 + y^2=z\)
\(x=\sqrt\frac{z-y^2}{3}\)
4)\(\frac{ab-\sqrt x}{3}=7\)
\(x=(ab-21)^2\)
5)\(5y(x+2)=z\)
\(x=\frac{z}{5y}-2\)
6)\(\frac{y+1}{x-2}+z^3=f\)
\(x=\frac{y+1}{f-z^3}+2\)
7)\(y=\frac{2x+1}{2x-1}\)
\(x=\frac{y+1}{2y-2}\)
8)\(4y=\frac{y-2x}{3x+2}\)
\(x=\frac{-7y}{12y+2}\)
