Step-by-step explanation:
Hope this photo will find you well
Good day!
<u>Part 1)</u> we have
------> equation A

------> equation B
Substitute the equation B in equation A
![5[12-3y]+2y=16](https://tex.z-dn.net/?f=5%5B12-3y%5D%2B2y%3D16)



Find the value of x
the best approximation is the point 
therefore
<u>the answer Part 1) is the option C</u>

<u>Part 2) </u>we have
------> equation A
------> equation B
equate equation A and equation B



Find the value of y
the solution is the point 
therefore
<u>the answer Part 2) is </u>
