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:
Option A: 6 to 9 , 9/12 is the correct answer.
Step-by-step explanation:
The equivalent ratios simplify to same simple ratio.
In case of this question, we have to check which to the ratios doesn't simplify to 3:4 or 3/4
Option A:
6 to 9 , 9/12
6 to 9 can be written as:
9/12 simplifies to 3/4
But as one of the ratio doesn't simplify to 3:4 which means 6 to 9 is not equivalent to 3:4
Hence,
Option A: 6 to 9 , 9/12 is the correct answer.
