Question

2 2/9-(x-1/6)= -1 1/3
3,2-(2 1/4 - x + 0,8)=3,6​

Answer 1

$1)$$2\frac{2}{9} -(x-\frac{1}{6} )=-1\frac{1}{3}$

$\frac{20}{9} -x+\frac{1}{6} =-\frac{4}{3}$

$\frac{43}{18} -x=-\frac{4}{3}$

$-x=-\frac{4}{3} -\frac{43}{18}$

$-x=-\frac{67}{18}$

$x=\frac{67}{18}$

$2)$$3,2(2\frac{1}{4} -x+\frac{4}{5})=3,6$

$\frac{16}{5}-(\frac{9}{4}-x+\frac{4}{5})=3,6$

$\frac{16}{5}-(\frac{61}{20}-x)=3,6$

$\frac{16}{5}-\frac{61}{20}=+x=3,6$

$\frac{3}{20}+x=3,6$

$x=3,6-\frac{3}{20}$

$x=\frac{18}{5}-\frac{3}{20}$

$x=\frac{69}{20}$
