# Systems of equations solver elimination

To solve by elimination of y, multiply the first equation by 5, and the second by 3, so that the equations become. 25x–15y=45 and 12x+15y=66. Now add the two equations together so you have 37x=111, so x=3. Now substitute x=3 into either of the original equations and find y=2. To solve a system of differential equations, borrow algebra's elimination method. Derivatives like d x /d t are written as D x and the operator D is treated like a multiplying constant. What is solving by elimination? You can solve by elimination when you eliminate either x or y by adding the two equations. We may need to rewrite one or both equations! Example: x = y + 1. y + x = 21. Let us rewrite x = y + 1 as x - y = 1 and then add the two equations to eliminate y. x - y = 1. y + x = 21. Let us add the two equations. 2x - y ...
