Dante wrote several equations and determined that only one of the equations has infinitely many solutions. Which of these equations has infinitely many solutions? 6 (x + 3) + x = 7 x + 2 + 1
6 (x + 3) + x = 7 x + 5
6 (x + 3) + x = 6 x + 3 + 15
6 (x + 3) + x = 7 x + 9 + 9

9514 1404 393

  6 (x + 3) + x = 7 x + 9 + 9

Step-by-step explanation:

The equation will have an infinite number of solutions if the left side is equal to the right side. The left side in each case is 7x+18.

The right sides are (in the order shown) ...

  = 7x +3

  = 7x +5

  = 6x +18

  = 7x +18 . . . . . . matches the left side

The equation 6 (x + 3) + x = 7 x + 9 + 9 will have infinitely many solutions.

the answer is true.
