Answer: Hope this helped(tried my best thinking what the question was asking)

x=0

y=-3

Step-by-step explanation:

(Im going to add and subtract)

Add:

14x-12y=36

14x+9y=-27

28x-3y=9

Subtract:

-14x+12y=-36

14x+9y=-27

21y=-63

y=-3 (substitute in first equation)

7x+18=18

7x=0

x=0

y=-3 and x=0

<h2>Fractions</h2>

Which expression is equal to $\large\tt \frac{4}{8}$ ?

Option 1

$\large \tt 4 \times \frac{1}{2} = \frac{4}{1} \times \frac{1}{2} = \red{\frac{4}{2}}$

Option 1 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 2

$\large \tt 3 \times \frac{1}{5} = \frac{3}{1} \times \frac{1}{5} = \red{\frac{3}{5}}$

Option 2 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 3

$\large \tt 3 \times \frac{1}{8} = \frac{3}{1} \times \frac{1}{8} = \red{\frac{3}{8}}$

Option 3 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 4

$\large \tt 4 \times \frac{1}{8} = \frac{4}{1} \times \frac{1}{8} = \green{\frac{4}{8}}$

Therefore, option 4 is equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$
