Bonsoir,
[tex] \frac{2(x + 3)}{x + 3} = \frac{2(x + 3)}{1(x + 3)} = \frac{2}{1} = 2[/tex]
[tex] \frac{5x(x + 4)}{(x + 4)(2 - x)} = \frac{5x}{(2 - x)} [/tex]
[tex] \frac{4x + 6}{2} = \frac{4x}{2} + \frac{6}{2} = 2x + 3[/tex]
[tex] \frac{5 {t}^{2} + 3t }{t} = \frac{5 {t}^{2} }{t} + \frac{3t}{t} = 5t + 3[/tex]
[tex] \frac{3x - 3}{x - 1} = \frac{3(x - 1)}{x - 1} = 3[/tex]
