Answer:
The system of equations is:
x + y = 15
xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
y = 15-x
x(15-x) = 15
15x - x� = 15
15x - x� - 15 = 0
-x� + 15x - 15 = 0
x� - 15x + 15 = 0
'of' means multiply
half a dozen means 12/2=6
6 of one thing means 6 times x
plus means ad
half a dozen of another mean 6 times y
they are added
6x+6y
2 variables
it says 'of the other' so they are diferent
