How to Solve Simultaneous Equations Using Substitution Method

So everywhere we see an x we can substitute it with a y minus 4 So let’s do that So if we substitute y minus 4 for x in this top equation the top equation becomes 2y is equal to instead of an x the second constraint tells us that x needs to be equal to y minus 4 So instead of an x we’ll write a y minus 4 and then we have a plus 7 All I.
