Boa tarde!!

$3x + \frac{x}{2} + x \\\\</p><p>\dfrac{3.2x}{2} +\dfrac{x}{2} +\dfrac{2x}{2} \\\\</p><p>\dfrac{6x +x +2x}{2} \\\\</p><p>\dfrac{9x}{2} \ \forall \ x\in \mathbb{R}$

Bons estudos!

Answer 2

$3x + \frac{x}{2} + x = \\ \\ \frac{2 \times 3x}{2} + \frac{1 \times x}{2} + \frac{2 \times x}{2} = \\ \\ = 6x + x + 2x \\ \\ = 7x + 2x \\ \\ = 9x$



Espero ter ajudado!
