Best ResponseYou've already chosen the best response.0x+y=7 2xy=8  3x  0 = 15 i though it was supposed to be 3x = 15 also, simplify it by dividing both sides by 3 and you get x = 5

Best ResponseYou've already chosen the best response.0Correct, you cross out the y but you forgot to add the x. you get as twilight mentioned 3x = 15 from there you divide by 3 to both sides to get your x value of 5.
