The sum of two numbers is 80 The difference is 16 Write and solve a system of equations to find the numbers.

32+48

Step-by-step explanation:

80- 32= 48

80-48= 32

 32; 48

Step-by-step explanation:

Let x be the smaller number, and y be the larger number, then we get

x + y = 80

x - y = 16

x - y = 16

x = 16 + y

x + y = 80

16 + y + y = 80

16 + 2y = 80

2y = 64

y = 32

x - y = 16

x - 32 = 16

x = 48

f(x) = y

f(-3) = -5
