Dante wrote several equations and determined that only one of the equations has infinitely many solutions. Which of these equati
ons has infinitely many solutions?
A.6(x+3)+x=7x+2+1
B.6(x+3)+x=7x+5
C.6(x+3)+x=6x+3+15
D.6(x+3)+x=7x+9+9
2 answers:
Answer:
D; 6(x + 3) + x = 7x + 9 + 9
Step-by-step explanation:
6x + 18 + x = 7x + 9 + 9
7x + 18 = 7x + 18
The equation has equivalent coefficients and constants on both sides, which proves that it has infinitely many solutions.
The answer is D I believe
