Best ResponseYou've already chosen the best response.2You need to find a common factor first 4x+5y = 5 8x+5y = 25 In this case it is 2 :) Bascially ask yourself which number will i need to multiply to get opposite x values that will cancel out \(\huge\rm\color{red}{2(4x+5y = 5)}\) Tell me the equation you get once you distribute

Best ResponseYou've already chosen the best response.2Thats correct good! :D \[\huge~\rm8x10y=10\] \[\huge~\rm~~~~~8x+5y = 25 \] Now just do simple math whats \(\huge\rm\color{red}{8+8=?}\)

Best ResponseYou've already chosen the best response.2Good so that cancels out :) 10+5= ?

Best ResponseYou've already chosen the best response.2good so we have 5y=15 i added the 10+25 ok now that we have that 5y=15 we divde both sides by 5 5 div 5=1 therefore x is alone now :P whats 15/5 ?

Best ResponseYou've already chosen the best response.2Yes thereofore our y value is 3 now we use substituion to figure out our x value \[\huge~\rm −8x−10(3)=−10\] solve for x

Best ResponseYou've already chosen the best response.2\[\huge~\rm~−8x−(10)(−3)=−10\] Simplify both sides of the equation. \[\huge~\rm~−8x+30=−10\] Subtract 30 from both sides. \[\huge~\rm~−8x+30−30=−10−30\]\[\huge~\rm~−8x=−40\] Divide both sides by 8 Take it from here :)
