Dante wrote several equations and determined that only one of the equations has infinitely many solutions. which of these equations 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

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.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
