Question

m=3-2n e n=-2 determine os numeros
3
a)-m+n
b)m+n-13
4

Answer 1

$a)-m+n = (3-2n)- \frac{2}{3}= 3-[2(\frac{-2}{3})- \frac{2}{3}]\\\\\ 3- [\frac{-2}{3}(2+1)]\\\\3+\frac{6}{3}=5$

$b)m+n=13=3-2(\frac{-2}{3})-\frac{2}{3}-(\frac{-13}{4})\\\\3+\frac{4}{3}-\frac{2}{3}+\frac{13}{4}\\\\3+\frac{2}{3}+\frac{13}{4}\\\\MMC: 36+8+39=83$
