Combine like terms by subtracting x from both sides.
x + 4 = 2x
4 = 2x - x
4 = x

(On one side, x-x cancelled out, and on the other side, the 2x-x works like normal subtraction so you are left with x. Therefore x is 4)

Step-by-step explanation:

To solve this problem

collect like terms

x-2x = -4

-x =-4

divide both sides of the equation by -

-x /- =-4

x=4

% distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
AB=\sqrt{(1-4)^2+(2-5)^2}\implies AB=\sqrt{(-3)^2+(-3)^2}
\\\\\\
AB=\sqrt{9+9}\implies \boxed{AB=\sqrt{18}}\implies AB=\sqrt{2(9)}

AB=\sqrt{2(3^2)}\implies \implies AB=3\sqrt{2}$
