For number one, the answer is C. (2,3).

For number two, the answer is (-1, -1). 

((Simply find the intersection between the two lines to get your solution.

Part 1) we have

\(5x+2y=16\) ------> equation A

\(x+3y=12\)

\(x=12-3y\) ------> equation B

Substitute the equation B in equation A

\(5[12-3y]+2y=16\)

\(60-15y+2y=16\)

\(13y=44\)

\(y=44/13=3.38\)

Find the value of x

\(x=12-3(44/13)=1.85\)

the best approximation is the point \((2.3)\)

therefore

the answer Part 1) is the option C

\((2.3)\)

Part 2) we have

\(y=-x-2\) ------> equation A

\(y=3x+2\) ------> equation B

equate equation A and equation B

\(-x-2=3x+2\)

\(4x=-4\)

\(x=-1\)

Find the value of y

\(y=-(-1)-2=-1\)

the solution is the point \((-1,-1)\)

therefore

the answer Part 2) is

\((-1,-1)\)
