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
Answer:
x + y = 15
xy = 15
Step-by-step explanation:
y = 15-x
x(15-x) = 15
15x - x ? = 15
15x - x ? - 15 = 0
-x ? + 15x - 15 = 0
x ? - 15x + 15 = 0
Hope you get it right!!
PLEASEEEE GIVE BRAINLIST!!!
