Question

h) x + 1/5 + 2x + 2/2 = 6
i) x + 2/2 + 2x + 2/3 = -10
j) x + 2/2 - 2x + 2/3 = -10
k) 3x + 1/4 - 2x - 5/3

Answer 1

Resposta:

descupa eu nao sei

Explicação passo-a-passo:

Answer 2

h)

$x+2x+\frac{1}{5} +\frac{2}{2} =6 \\\\ 3x+\frac{1}{5}+1=6 \\\\= 3x=5-\frac{1}{5} \\\\3x=\frac{24}{5}\\\\x=\frac{24}{15} =\frac{8}{5}$

i)

$x+2x+\frac{2}{2}+ \frac{2}{3}=-10\\ \\3x+1+\frac{2}{3}=-10\\\\3x=-11-\frac{2}{3}\\\\3x=\frac{-33-2}{3}\\\\x=\frac{-35}{9}$

j)

$x-2x+\frac{2}{2}+\frac{2}{3}=-10\\\\-x=-11-\frac{2}{3}\\\\-x=\frac{-35}{3}\\\\\\x=\frac{35}{3}$

k)

$3x-2x+\frac{1}{4}-\frac{5}{3}\\\\x=\frac{5}{3}-\frac{1}{4}\\\\x=\frac{20-3}{12} \\\\x=\frac{17}{12}$
