omgz i did this today!!
X+Y=11 (equation 1) 2X+8Y=52 (equation 2) X+Y=11 (x 2) 2X+2Y=22 (equation 3) 2X+2Y=22 ( 2X+8Y = 52 (equation 2 - equation 3) 2X+8Y = 52 - 2X+2Y=22 6Y = 30 (divide by 6) Y = 5 sorry had to use my book took awhile and too find X u have to do what y is in the formula so X+Y=11 (-5) X = 6 so vicky is wrong as x = 6 and y = 5 Last edited by MeMyselfAndI; 09-11-2010 at 06:44 PM. |
