how many solutions does this equation have
y = 3x + 6
y = -13x - 4
This system of equations is linear and can be solved for x and y. To find the solution, we can set the two equations equal to each other and solve for x:
3x + 6 = -13x - 4
16x = -10
x = -10/16
x = -5/8
Now that we have found x, we can substitute it back into one of the equations to find y:
y = 3(-5/8) + 6
y = -15/8 + 48/8
y = 33/8
Therefore, the solution to the system of equations is x = -5/8 and y = 33/8. This system of equations has a unique solution.
