Question

determine o conjunto solução das equações, considerando u=q

3x-$\frac{5-3x}{2}$=2(x-5)

Answer 1

$3x - \dfrac{5 - 3x}{2} = 2(x - 5) ~~~~~~~~~ (\cdot2) \\ \\ \\ 6x - (5-3x) = 4(x-5) \\ \\ 6x - 5 + 3x = 4x - 20 \\ \\ 6x + 3x - 4x = -20 + 5 \\ \\ 5x = -15 \\ \\ x = -\dfrac{15}{5} \\ \\ \boxed{x = -3}$

$\boxed{S = \{-3\}}$

Answer 2

$3x-\dfrac{5-3x}{2}=2(x-5)$

$6x-5+3x=4(x-5)$

$9x-5=4x-20$

$9x-4x=-20+5$

$5x=-15$

$x=-3$

$S=\{-3\}$
