Best ResponseYou've already chosen the best response.00.3x0.2y=4 0.5x+0.3y=71/23 so, first you have to get rid of the y from both equations

Best ResponseYou've already chosen the best response.0right! i'm clueless, the fraction throws me off!

Best ResponseYou've already chosen the best response.0It is simple: multiply both equations, so that the y members of both of them are eliminated when added so in your case, we can multiply the first equation by 3, to get 0.9x0.6y=12 and now we need to multiply the second equation in such a way that when coresponding members of both of them are added, y is eliminated (equals zero) so, we have to multiply it by 2 to get 1x+0.6y=142/23

Best ResponseYou've already chosen the best response.0now, we have to add all coresponding members to eliminate y, so 0.9x0.6y=12 + 1x+0.6y=142/23 _________________________ 1.9x+0=418/23 =1.9x=418/23

Best ResponseYou've already chosen the best response.0so, now lets solve for x 1.9x=418/23 23*1.9x=418 43.7x=418 x=418/43.7 x=9.56521

Best ResponseYou've already chosen the best response.0i have to solve it as a fraction, so i'm plugging in 418/43.7 to solve for y ....

Best ResponseYou've already chosen the best response.0now to get y we just take any equation, and substitute x into it, and solve for y 0.3x0.2y=4 0.3*9.565210.2y=4 2.8695652170.2y=4 0.2y=42.869565217 0.2y=1.130434 y=1.130434/0.2 y=5.65

Best ResponseYou've already chosen the best response.0to get it as a fraction, just do same steps as I showed you, just keep pluging in fractions all the way from the beginning until now, and you can get a fraction
