Answer:
S(7, -37)
Step-by-step explanation:
Let the coordinates of point S be (x, y).
(14 + x)/2 = 7
14 + x = 14
x = 0
(21 + y)/2 = -8
21 + y = -16
y = -37
the answer is 6 i think
i dont know what it means by expand but i will simplify it
it would simplify to 16x-18
5(2x-1) + 2(3x-6)
10x-5+6x-12
10x+6x-5-12
16x-18
