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

Deidre is working with a function that contains the following points these are the X values these are y values and they ask us is this function linear or nonlinear so linear functions the way to tell them is for any given change in x is the change in y always going to be the same value for example if when x went for any one step change in x is the change in y always going to be 3 is it alwaysWhat is a linear function? · Graphs linear equations and functions 1 Graphs, Linear Equations 2• The function y = 3 x − 2 is not defined for values < 3 36 37 35 Introduction to FunctionsIdentifying functions defined by graphsand equationsVertical Line TestIf every
