Pls help me i’m so stuck

just flip the triangle in y=-x brah

Step-by-step explanation:

Let,y =  the time to dancex = time for mathtotal time spent on practicing dance and math = 80 minutes  extra time for dance = 20 minutespart a: write a pair of linear equations: x + y = 80 (total time spent on dance and math)and  y = x + 20 (extra 20 minutes for dancing)part b: time spent on practicing math:   replace y = 20+x in the first equationwe get,x + 20 + x = 80combining like terms2x = 60dividing both sides by 2x = 30 minutes  part c: is it possible for pam to have spent 60 minutes practicing dance every day? explain your reasoning.  no. because she practices math for 30 minutes; so she spends 20 minutes more on practicing dance, which means she spends: 30min + 20 min = 50 minutes on practicing dance.
