B, infinite solutions if x = x
Answer:
x = 4
Step-by-step explanation:
change the signs on both sides of the equation
7-4x= - 9
move constant to the right side and change its sign
- 4x = - 9 - 7
-4x= - 16
divide both sides of the equation by -4
x = 4

mia's mean= 34.33
sophia's mean= 35.667
sophia-mia= 1.33
