Best ResponseYou've already chosen the best response.0Ok so because you are using substitution you want to get either y or x by itself. Which one would you like to get by itself?

Best ResponseYou've already chosen the best response.0Alright so... 3x=2y5 divide each side by 3 to get x alone x=2/3y5/3

Best ResponseYou've already chosen the best response.0Now you can take this and plug it into your other equation to substitute for x. 2y=5x+5 2y=5(2/3y5/3 )+5 2y=10/3y+40/3 combine like terms (so subtract 10/3y from both sides) 4/3y=40/3 divide each side by 4/3 y=10

Best ResponseYou've already chosen the best response.0Now that you know your y value take y, which is 10 and plug it into your original equation 3x=2y5 3x=2(10)5 3x=205 3x=15 divide each side by 3 x=5
