The answer would be option B

Belinda Wheeler · Answer 2

The correct answer option is a) there are an infinite number of solutions

Step-by-step explanation:

We are given these two following equations:

15x = 5y - 5 - - - (1)

y = 3x + 1 - - - (2)

Solving these two by the substitution method by putting the value of y in equation (1).

15x = 5y - 5

15x = 5 (3x + 1) - 1

15x = 15x + 5 - 5

5 and - 5 get cancelled and we are left with 15 on both sides of the equation which will cancel each other.

Therefore, these equations have an infinite number of solutions.
