The slope of the line = 50
He has half of the money because 1-1/2 = 1/2
Subtract 6 on both sides


Multiply -2 on both sides to get "x" by itself

x = -8
The correct answer is x = -90.
To find this, solve using the order of operations. See the example below.
x/-3 - 41 = -11 ----> Add 41 to both sides
x/-3 = 30 ----> Multiply each side by -3
x = -90
