Example

x + 3

- 7 + \frac{3}{4}

x+3=-7+(3/4)

7 - 2.4 (x + 1)

2 - 3 x

7-2.4*(x+1)=2-3*x

x + \frac{5}{2}

0

x+5/2=0

\frac{x}{2} - \frac{y}{3 - x}

0

(x/2)-(y/(3-x))=0

\sqrt{x - 1}

5

sqrt(x-1) = 5

\frac{a}{5} + (\frac{a - 2}{2})

7

(a/5)+((a-2)/2)=7

3 x^{2} - 4 x + 7

0

3*x^2-4*x+7=0

\frac{x^{2} - 4}{x - 2}

x^{2} - 4 \cdot x + 7

(x^2-4)/(x-2)=x^2-4*x+7

2 \cdot x^{3} - \frac{3 \cdot x^{2}}{2} + \frac{1}{2}

0

2*x^3-(3/2)*x^2+1/2=0

\sin (x)

- 5 + \cos (π)

sin(x)=-5+cos(π)
