ex 11 Va rog e urgent dau ce vreti si va ajut!!!Nu trebuie neaparat tot ex macar 1 subpunct

Answer 1

d)$\frac{x-5}{44}= \frac{9}{19a}$

19a:11  deci a = 8  deci  19a devine 198


$\frac{x-5}{44}= \frac{9}{198} \\ \\ 198(x-5)=9\cdot44 \\ \\ 198x-198\cdot5=396 \\ \\ 198x=396+990 \\ \\ 198x=1386 \\ \\ x=1386:198 \\ \\ x=7$
