First you would want to add all like terms. So add -2x and -x which will give you the equation -3x+8=?. Now you want to get 8 on the other side to simplify the equation even more so subtract 8 on both sides. -3x=-8. Finally you want to isolate x by dividing by -3 on both sides which will leave you with x=8/3 or x=2 2/3
The scale of the map from inches to miles is 1 inch : 9 miles
<h3>How to determine the scale of the map from inches to miles?</h3>
The given parameters are:
- The actual distance of the cities apart = 36 miles
- The scale distance of the cities apart = 4 inches
The scale of the map from inches to miles is represented as:
Scale of map = The scale distance of the cities apart : The scale distance of the cities apart
Substitute the known values in the above equation
Scale of map = 4 inches : 36 miles
Divide both sides of the ratio by 4
So, we have:
Scale of map = 4/4 inches : 36/4 miles
Evaluate the quotient
Scale of map = 4/4 inches : 9 miles
Evaluate the quotient
Scale of map = 1 inch : 9 miles
Hence, the scale of the map from inches to miles is 1 inch : 9 miles

Step-by-step explanation:
180 - y + z = x {Exterior angle property}
z = x - 180 + y
z = x + y - 180
