How to solve the equation of (x-46.5) + (x-38.8) = x

How to solve the equation of (x-46.5) + (x-38.8) = x


(X-46.5)+(X-38.8)=X
x-46.5+x-38.8=x
x+x-46.5-38.8-x=0
x+x-x=46.5+38.8
x=85.3.



The solution of (1-1 / 3) * (42-x) = 29-x equation


(1-1 / 3) * (42-x) = 29-x
2/3*(42-x)=29-X
2(42-x)=3(29-X)
84-2x=87-3x
x=3
