Answer 1

Answer:

$1. \: x = 2 \\ y = 1 \\ z = - 3 \\ = x + y + z \\ = 2 + 1 + ( - 3) \\ = 3 + ( - 3) \\ = 3 - 3 \\ = 0$

$2. \: \frac{8}{9} \times \frac{1}{1} = \frac{8}{9} \\ \frac{8}{9} \times \frac{2}{2} = \frac{16}{18} \\ \frac{8}{9} \times \frac{3}{3} = \frac{24}{27} \\ \frac{8}{9} \times \frac{4}{4} = \frac{32}{36}$

$3. \: 100 - ( - 33) \\ = 100 + 33 \\ = 133$

$4. \: a = 3 \\ b = 2 \\ c = - 3 \\ b \times (a + c) = b \times a + b \times c \\ = 2 \times (3 + ( - 3)) = 2 \times 3 + 2 \times ( - 3) \\ = 2 \times (3 - 3) = 6 + ( - 6) \\ = 2 \times 0 = 0 \\ = 0 = 0$

hope this helps you

thank you

Answer 2

x=2

y=1

z=−3

=x+y+z

=2+1+(−3)

=3+(−3)

=3−3

=0

\begin{gathered} 2. \: \frac{8}{9} \times \frac{1}{1} = \frac{8}{9} \\ \frac{8}{9} \times \frac{2}{2} = \frac{16}{18} \\ \frac{8}{9} \times \frac{3}{3} = \frac{24}{27} \\ \frac{8}{9} \times \frac{4}{4} = \frac{32}{36} \end{gathered}
