Answer:
x=-15/2, y=1/8. (-15/2, 1/8).
Step-by-step explanation:
3x+4y=-22
x-4y=-8
------------------
4x=-30
x=-30/4
simplify
x=-15/2
-15/2-4y=-8
4y=-15/2-(-8)
4y=-15/2+8
4y=-15/2+16/2
4y=1/2
y=(1/2)/4
y=(1/2)(1/4)
y=1/8
Let the nomber of 2 pointers be x and that of 3 pointers be y, then
2x + 3y = 30 . . . (1)
x = y + 5 . . . (2)
Putting (2) into (1), gives 2(y + 5) + 3y = 30
2y + 10 + 3y = 30
5y = 30 - 10 = 20
y = 20/5 = 4
x = 4 + 5 = 9
2.5 x 2.5 x 2.5 = 15.625 same as 2.5 to the third power
