Best ResponseYou've already chosen the best response.03x + 9y = 7 ......solving for x....subtract 9y from both sides 3x = 9y  7....now we would divide both sides by 3 x = (9y  7) / 3 or x = 3y  7/3 3x + 9y = 7 ....solving for y....subtract 3x from both sides 9y = 3x  7 ....now we will divide both sides by 9 y = (3x  7) / 9 or y = 1/3x  7/9
