Question

Y=9x-5 y=9x+6 how many solutions does the system have?

Answer 1

To find the amount of solutions, solve the system.

y = 9x - 5
y = 9x + 6

Both equations equal y so you can set them equal to each other to solve for x.

9x - 5 = 9x + 6
-5 ≠ 6

Negative five is not equal to six, so this system has no solutions.
