Elimination Method in Algebra: Definition & Examples

WebThe elimination method is a technique for solving systems of linear equations. Let's walk through a couple of examples. Example 1 We're asked to solve this system of equations: \begin {aligned} 2y+7x &= -5\\\\ 5y-7x &= 12 \end {aligned} 2y + 7x 5y − 7x = −5 = 12 WebSo negative 10x is equal to 0. Divide both sides by negative 10, and you get x is equal to 0. And now we can substitute back into either of these equations to figure out what y must be equal to. Let's substitute into the top equation. So we get 5 times 0, minus 10y, is equal to 15. Or negative 10y is equal to 15. download mod for hoi4
