Answer:
The solutions are 3 and -5
Step-by-step explanation:
x+3=x^2+3x-12
x^2+2x-15
=(x-3)(x+5)
y = x² + 3x - 12
y = x + 3
Substitute the second value of y into the first equation, and you'll have
x + 3 = x² + 3x - 12
Now solve
0 = x² + 2x - 15
0 = (x + 5)(x - 3)
x = - 5, x = 3
With -5, you'll get y = - 2
With 3, you'll get y = 6
