Step-by-step explanation:
Because if you take 2 and put it in the place of n 32+12 =45 and take 45 and divide it by 12 and you will get 11.
It is a process of this activitie
The graph graphed is y=1/2x
so
y=1/2x and y=-x+6
y=y so
1/2x=-x+6
times 2 both sides
x=-2x+12
add 2x both sides
3x=12
x=4
sub back
y=1/2x
y=1/2(4)
y=2
(4,2) is the solution
