Answer 1

Respuesta:

e. n=$\frac{47}{36}$

f.r=$\frac{74}{315}$

g.t=$\frac{145}{6}$

h.x=-$\frac{77}{12}$

Explicación paso a paso:

e.

$\frac{3}{4}+\frac{1}{3} =n-\frac{2}{9} \\\\\frac{13}{12}=n-\frac{2}{9}\\\\-n=-\frac{2}{9} -\frac{13}{12} \\\\-n=-\frac{47}{36} \\\\n=\frac{47}{36}$

f.

$-\frac{1}{7} +\frac{3}{5}-r=\frac{2}{9}\\\\\frac{16}{35}-r=\frac{2}{9} \\\\-r=\frac{2}{9} -\frac{16}{35} \\\\-r=-\frac{74}{315} \\\\\\r=\frac{74}{315}$

g.

$\frac{2}{5}t-\frac{8}{3} =7\ ) =15x7\\\ 6t-40=105\\6t=105+40\\6t=145 \\t= \frac{145}{6}$

h.

$\frac{12}{7} x+3=-8\\12x+21=-56\\12x=-56-21\\12x=-77\\x=-\frac{77}{12}$
