Objective:Solve systems of linear equations using elimination Example 1) 3 x + 2 y = 2 -3 x + 2 y = 6 Add the equations 4 y = 8Simplify y = 8/4 = 2 Substitute using y = 2 3 x + 2(2) = 2 3 x + 4 = 2Simplify 3 x =
To solve a system by elimination, add or subtract the equations of the system in order to "eliminate" one of the variables. Continue this process until only one variable is known. Then, substitute this known variable into the preceding equations to find the remaining variables. What is the ...

system of equations -2x + 2y = 4 2x + y = 5 3y = 9 33 y=3 2x + (3) = 5 - 3 -3 2x = 2 22 x=1 -2x + 2(3) = 4 -2x + 6 = 4 - 6 -6 -2x = -2 -2 -2 x=1 If two equations are in standard form a system can be solved by ELIMINATION instead of ...
Here I've got two. Can I get rid of one of these variables in the system, just as I'd have gotten rid of the −6 in the equation? Looking at the system of equations they've given me, I see that I've got a +y in the first line, and a −y in the second line. If I...
