Are you trying to solve for x?

%28x-11%29%2Fx=.31 Start with the given equation


x-11=.31x Multiply both sides by x


-11=.31x-x Subtract x from both sides


-11=-0.69x Combine like terms on the right side


%28-11%29%2F%28-0.69%29=x Divide both sides by -0.69 to isolate x


15.94203=x Divide


So our answer is x=15.94203
