Question

Help please I’m so confused!

Answer 1

Three Ways how to solve- by graphing or using process of elimiation or process of :substitution

Line 1: 3x -y =6

Line 2: 4x +4y = -8

Substitution Method:

y = 3x - 6 (make line 1 equal to x)

then plug it as y into line 2 formula

4x + 4(3x - 6) = -8  

Now solve

4x + 12x -24 = -8

16x = 16

x = 1

Elimination Method:

3x -y =6  (multiply the top by 4 to get rid of y )

4x +4y = -8

So, it changes to ...

12x - 4y = 24

4x +4y = -8

then add

16x = 16

x = 1

Graphing:

Plot both equations, then find the point where they intercept and find the x value and that should be your answer

The graph is attached.

x = 1

Answer 2

(-1,-3) i will got for C.
