Answer:
2 one.
Step-by-step explanation:
The system has one solution because the slopes are different. TO solve...
5x - 6y = -25
4x - 3y = -20, multiply this equation by -2
5x - 6y = -25
-8x + 6y = 40, now use combination to get
-3x = 15, so x = -5. Now plug this back into either original equation to get
5*(-5) - 6y = -25
-6y = 0, so y = 0, so the solution is (-5,0)
