How much did John invest in each type of fund? In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. Pick another pair of equations and solve for the same variable.

I have been able to manipulate and solve for the indicated variable in these type of equations pretty easily until I came across this one. I know that I have to isolate $x$ on one side but I am having trouble with it. Would dividing both sides by $(a+1) $ be the proper first step?
Sal solves the equation P=2I+2w for the variable I. So we have P is equal to 2 times l plus 2 times w. So we need to solve for l. So let's isolate all of the l terms on one side. And the best way, we could just do that by leaving it here on the right and then getting rid of this 2w.
