Question

Resolva a equação de 1 grau a seguir: 10-3(2/2-x) + 2 (x/3 - 1) = 2/5

Answer 1

Explicação passo-a-passo:

$10 - 3( \frac{2}{2} -x) + 2( \frac{x}{3} - 1) = \frac{2}{5}$

$10-3+3x+ \frac{2x}{3}-2= \frac{2}{5} \\ 3x + \frac{2x}{3} + 5 = \frac{2}{5} \\ \frac{3x}{3} + \frac{2x}{3} + 5 = \frac{2}{5} \\ \frac{5x}{3} + 5 = \frac{2}{5} \\ 25x + 25 = 6 \\ x = \frac{ - 19}{25}$
