Answer 1

Explicación paso a paso:

1.a)

$a+(-\frac{8}{3} )=23\\a+(-\frac{8}{3} )+\frac{8}{3} =23+\frac{8}{3}\\\\a=23+\frac{8}{3}\\\\a=\frac{77}{3}$

1.b)

$2y+(-\frac{5}{4}) =0,75\\2y-(\frac{5}{4}) =0,75\\2y-(\frac{5}{4})+(\frac{5}{4}) =0,75+(\frac{5}{4})\\2y=0,75+(\frac{5}{4})\\2y=0,75+1,25\\2y=2\\y=\frac{2}{2}\\y=1$

1.c)

$18x=\frac{1}{3}\\x=\frac{\frac{1}{3} }{\frac{18}{1} } \\x=\frac{1}{54}$

1.d)

$m-5=\frac{2}{7} \\m-\frac{35}{7}=\frac{2}{7} \\m=\frac{2}{7}+ \frac{35}{7} \\m=\frac{37}{7}$
