Question

resolva a equação 3(×-5)/6+2×/4=7, me ajudemmmmmm​

Answer 1

$\: \frac{3(x \: - \: 5)}{6} \: + \: \frac{2x}{4} \: = \: 7$

$\frac{1}{2}x \: + \: \frac{ - 5}{2} + \: \frac{2x}{4} \: = \: 7$

$\frac{1}{2}x \: + \: \frac{ - 5}{2} \: + \: \frac{1}{2}x \: = \: 7$

$( \frac{1}{2}x \: + \: \frac{1}{2}x) \: + \: ( \frac{ - 5}{2}) \: = \: 7$

$x \: + \: \frac{ - 5}{2} \: = \: 7$

$x \: + \: \frac{ - 5}{2} \: + \: \frac{5}{2} \: = \: 7 \: + \: \frac{5}{2}$

$x \: = \: \frac{19}{2}$
