Answer:
B. infinitely many solutions
Step-by-step explanation:
–2(–x + 9) = 2(x – 9)
Distribute the -2 on the left side. Distribute the 2 on the right side.
2x - 18 = 2x - 18
Add 18 to both sides.
2x = 2x
The equation means two times a number x is equal to two times the same number x. This is true for all numbers x. Every number is a solution of this equation.
