Solving linear equations by addition
WebUse elimination to solve for x and y. And they gave us two equations here-- x plus 2y is equal to 6 and 4x minus 2y is equal to 14. So to solve by elimination, what we do is we're going to add these two equations together so that one of the two variables essentially gets eliminated, gets canceled out. WebFeb 4, 2013 · 4.

WebPlus 2. The left-hand side just becomes an x. You have a less than or equal sign. That won't change by adding or subtracting the same thing to both sides of the inequality. And then 1 plus 2 is 3. So x needs to be less than or equal to 3. Any x that is less than or equal to 3 will satisfy this equation. fish and chips in bend orWebThere are a few ways to solve this, but I'll tell you how I did it. Since I find graphing my equations easier, I decided to put both these equations in y=mx+b form. For -6x+3y=-18, solve for y by adding 6x to both sides, and you get 3y = 6x + 18.
