Answer 1

Explicație pas cu pas:

$\space$

$\bf x + 2x + ^{2)}\frac{x}{2} + \frac{x}{4} = 150 \\ \\ \bf 3x + \frac{2x}{4} + \frac{x}{4} = 150 \\ \\ \bf ^{4)}\frac{3x}{1} + \frac{3x}{4} = 150 \\ \\ \bf \frac{12x}{4} + \frac{3x}{4} = 150 \\ \\ \bf \frac{15x}{4} = 150 \\ \\ \bf 15x = 150 \cdot 4 \\ \\ \bf 15x = 600 \\ \\ \bf x = \frac{600}{15} \implies \red{ \boxed{ \bf x = 40} }$
