Answer:
x = -9
y = -8
Step-by-step explanation:
here's the solution :-
=》y = 2x + 10
=》y = x + 1
plunging the value of y from equation 1 into equation 2
=》2x + 10 = x + 1
=》2x - x = 1 - 10
=》x = -9
value of x = -9
now, plugging the value of x in equation 2, we get :-
=》y = x + 1
=》y = -9 + 1
=》y = -8
Answer:

Step-by-step explanation:
0.05n+0.01p=0.80
-0.01(n+p=28)
0.05n+0.01p=0.80
-0.01n-0.01p= -0.28
0.04n=0.52
n=13
p=15
