Answer:
18-x
Step-by-step explanation:
|x-18| = x-18, if x-18 > 0 <=> x > 18
|x-18| = 18-x, if x-18 < 0 <=> x < 18
X= -5
Convert the sentences into equations.
Set those equations equal to each other.
6x+21=3x+6
Solve for x.
To Find the midpoint, add the 2 X coordinates together and divide by 2 and then do the same with the Y coordinates:
X: 3+7 = 10 / 2 = 5
Y = -5 + 9 = 4 / 2 = 2
The midpoint is (5,2)
