Best ResponseYou've already chosen the best response.2Add the 1st equation to the negative of the 2nd equation. What do you get?

Best ResponseYou've already chosen the best response.0Y= 2x + 1 and Y= 4x  1

Best ResponseYou've already chosen the best response.2Like this 2x + y = 1 plus (4x + y = 1) equals 2x (4x) + y  y = 1 (1) Do you see what happened here?

Best ResponseYou've already chosen the best response.2So what do you think we should do with that last equation?

Best ResponseYou've already chosen the best response.2How can we simplify this  2x (4x) + y  y = 1 (1) ?

Best ResponseYou've already chosen the best response.2See the y  y will cancel to become zero $$ 2x (4x) + 0 = 1 (1)\\ $$ What's else can we do?

Best ResponseYou've already chosen the best response.0subtract the values and get 6x

Best ResponseYou've already chosen the best response.2Close The (4x) becomes just 4x: $$ 2x +4x + 0 = 1 (1)\\ $$ Now what?

ybarrap

Best ResponseYou've already chosen the best response.2yes! So now we have $$ 2x+0=1(1) $$ What's can we do next?

Best ResponseYou've already chosen the best response.2(1) = 1 Remember, negative of a negative number makes it positive Try again

Best ResponseYou've already chosen the best response.2$$ 2x+0=1(1)=1+1 $$ Do you see that? What's next?

Best ResponseYou've already chosen the best response.2yes! Ok, what do we do now?

Best ResponseYou've already chosen the best response.2We need x by itself, what do we need to divide out on both sides to make 2x equal to just x ?

Best ResponseYou've already chosen the best response.02 divided by both sides

ybarrap

Best ResponseYou've already chosen the best response.2Yes! We need to divide 2 to both sides: $$ \cfrac{2x}{2}=\cfrac{2}{2}=? $$ What does this give us for x?

Best ResponseYou've already chosen the best response.2Yes! Now you know one variable. Now let's use one of your original equations to get y Let's use this one $$ 2x + y = 1 $$ Plug in x=1 and see what you get for y.

Best ResponseYou've already chosen the best response.2$$ 2\times 1 + y = 1 $$ So now what is y?

ybarrap

Best ResponseYou've already chosen the best response.2$$ 2\times 1 + y = 2+y=1 $$ See that?

Best ResponseYou've already chosen the best response.2Add 2 to both sides of this equation $$ 2+y+2=1+2 $$ What does this give us?

ybarrap

Best ResponseYou've already chosen the best response.2Almost there $$ 2+2+y=3 $$

ybarrap

Best ResponseYou've already chosen the best response.2Yes! So now you know everything. x=1 y=3 (1,3)
