distribute the value of x,y, and z, on the given questions, and then you do multiplication, next addition, lastly lowest term.
The distributive property: a(b - c) = ab - ac

Answer:
72 adult tickets were sold and 114 child tickets were sold.
Step-by-step explanation:
x+y=186, 14x=10y=2148
x=186-y
14(186-y)+10y=2148
2604-14y+10y=2148
2604-4y=2148
-4y=-456
y=144
x=186-144 : x=72
Point-slope form is y-y1=m(x-x1)
m=1
y1=11
x1=-2
y-11=1(x-(-2)
