<span>The answer is x=<span>−<span><span>1<span> and </span></span>y</span></span></span>=<span>6. You can solve it using a graph, substitution, or elimination. </span>
So you are given what x and y are. All you have to do is substitute and simplify. Since y = -3x + 3 The y value in the first equation can be substituted for -3x + 3 I.e. x = - (-3x + 3) + 5 So where you see 'y' in the first equation, put in what y actually is. Now simplify x = 3x - 3 + 5 [two minuses makes a positive] x = 3x + 2 -2x = 2 so x = 2/-2 = -1
With the value of x you found, substitute it in to find y I.e. y = -3(-1) + 3 y = 3 + 3 = 6
