Question

Determine o valor da incógnita t da equação abaixo *
(t+3)/2+t+2/3=-1/3

Answer 1

Resposta:

Explicação passo-a-passo:

$(\frac{t}{2} +\frac{3}{2}) +t +\frac{2}{3} = -\frac{1}{3} \\\frac{t}{2} + t = -\frac{3}{2} -\frac{2}{3} -\frac{1}{3}$

$*fazendo\\\frac{t}{2} +t = \frac{t}{2} +\frac{t}{1}= \frac{(t+2t)}{2} = \frac{3t}{2}$  

$-\frac{3}{2} -\frac{2}{3} -\frac{1}{3} = \frac{(-9-4-2)}{6} = -\frac{15}{6}$

$\frac{3t}{2} = \frac{-15}{6} \\\\t=\frac{-15}{6}/\frac{3}{2}\\\\t=\frac{-30}{18}\\\\t=-\frac{5}{3}$
