How do i solve by substituting x +y = 6y = 4

Since we alredy know that y = 6 we can go ahead and insert it into the problem. It would look like this:

x + 4 = 6

Now we can begin to solve.

Since positive 4 is on one side, we can subtract it from both sides

It will look like this:

x + 4 = 6

x - 4 = 6 - 4

You end up with

x = 2

Now substitute all your known variables.

It will look like

2 + 4 = 6

This equation is true.
