Best ResponseYou've already chosen the best response.2The 7 + 7 will cancel out.. so you're left with just 3x so we know dw:1433428826676:dw Now what does 1 + 7 = ?

Best ResponseYou've already chosen the best response.2yes so now we have: dw:1433428973058:dw Now what does: 3x  2x = ?

Best ResponseYou've already chosen the best response.2yes exactly :) so : dw:1433429128261:dw Now that we know x = 8.. we need to find out what y equals to... To do this plug x = 8 into one of the original equations dw:1433429158638:dw

Best ResponseYou've already chosen the best response.2So if we use the equation y = 2x +1 and we plug in x = 8 we will get: y = 2x + 1 y = 2(8) + 1 y = ?

Best ResponseYou've already chosen the best response.2yeeeess!!! y = 17 SO to sum it up x = 8 , y = 17 And we're done :) Now put it in the form (x, y ) > (8, 17)
