Answer: The answer is x=6, the final set of (x,y) values are (6,-4)
Explanation:
You must move around the equation to get it to y= mx+b to find the (x,y) values
Since you know y=-4 since it is stated above, plug in -4 for all y values and solve.
1. 6x+ 7(-4) =4x +4(-4)
2. 6x -28= 4x -16
3. 2x-28=-16
4. 2x=12
5. x=6
