Xy = 2 x y = 2 −xy = −4 x y = 4 Add the two equations together to eliminate x x from the system Divide each term in 2y = −2 2 y = 2 by 2 2 and simplify Tap for more steps y = −1 y = 1 Substitute the value found for y y into one of the original equations, then solve for x x Tap for more steps x = 3 x = 3The elimination method for solving systems of linear equations uses the addition property of equality You can add the same value to each side of an equation to eliminate one of the variable terms latex\begin{array}{r}2xy=12\,\\3x–y=−2\\5x=10\,\\x=2\,\,\,\,\end{array}/latex Substitute latexy=2/latex into one of the original By adding the two equations together you eliminate the y variable which allows you to solve x = 6 Alternately, subtract one equation form the other eliminating the x and allowing y = 4 Explanation Given 1 XXXx y = 10 2 XXXx −y = 2 Add 1 and 2 3 XXX2x = 12 → 4 XXXx = 6 Subtract 2 from 1 5 XXX2y = 8 → XXXy = 4 Answer link
