2/5 (x-4) = 2x
We simplify the equation to the form, which is simple to understand
2/5 (x-4) = 2x
Simplifying:
+ 0.4 * (x-4) = 2x
Reorder the terms in parentheses
+ ( + 0.4x-1.6) = 2x
Remove unnecessary parentheses
+ 0.4x-1.6=+2x
We move all terms containing x to the left and all other terms to the right.
+ 0.4x-2x=+1.6
We simplify left and right side of the equation.
-1.6x=+1.6
We divide both sides of the equation by - 1.6 to get x.
x=-1
