Bot GPT 3.5 To determine the number of solutions, we can solve the given system of equations using the method of substitution:
First, solve the first equation for y:
y = 5x + 7
Substitute this value of y into the second equation:
3(5x + 7) - 15x = 18
15x + 21 - 15x = 18
21 = 18
The equation 21 = 18 is not true, which means there is no solution to the system of equations. Therefore, the given system of equations has 0 solutions.
