Question 145179
The first step in the substitution method is to solve one of the equations for one of the variables in terms of the other(s).  That has already been done for you, so the hardest part is over.


If you look carefully at your first equation, you see that you have a statement that {{{x}}} is equal to something, namely: {{{4-4y}}}.  That means you can substitute this something for {{{x}}} anywhere you see it in the second equation, thus:


{{{-green(x)+2y=2}}}, so {{{-green((4-4y))+2y=2}}}.


Solve the derived equation for {{{y}}}, and then you can substitute the value you find into either of the given equations in order to solve for {{{x}}}.


Once you have the two values, express your answer in the form of an ordered pair ({{{x}}},{{{y}}}).


To check your answers, substitute the values for {{{x}}} and {{{y}}} from your solution into each of the given equations.  If you have the correct values for the {{{x}}} and {{{y}}} coordinates, you will get a true statement in each case.
