Question

3X/2+2=3X-2
E
X+2/3 - 4-5x/2 = 3X-5/4 + 1/3
POR FAVOR ME AJUDEM! PRECISO DA RESPOSTA ATE AMANHÃ, DETALHADA E EXPLICANDO PASSO A PASSO.

Answer 1

Explicação passo-a-passo:

$\frac{3x}{2}+2=3x-2\\\frac{3x+2}{2}=3x-2\\3x+2=2*(3x-2)\\3x+2=6x-4\\2-4=6x-3x\\-2=3x\\x=-\frac{2}{3}$

$x+\frac{2}{3}-4-\frac{5x}{2} =3x-\frac{5}{4}+\frac{1}{3} \\x-\frac{5x}{2}-3x=-\frac{5}{4}+\frac{1}{3}-\frac{2}{3}+4\\\frac{3x}{2} -3x=-\frac{5}{4}+\frac{1}{3}-\frac{14}{3}\\-\frac{3x}{2}=\frac{-15+4-56}{12}\\ -\frac{3x}{2}=\frac{45}{12}\\x=\frac{45*2}{12*(-3)} \\x=-\frac{90}{36} \\x=-\frac{5}{2}$
