Web17 mei 2016 · @Joana Yes--these are called non-linear equations, such as x 2 + 5 x + 4 = 0. These are solved (algebraically) by transforming them into linear equations: x 2 + 5 x + 4 = ( x + 1) ( x + 4) therefore if ( x + 1) ( x + 4) = 0 then it's solved if x + 1 = 0 → x = − 1 or if x + 4 = 0 → x = − 4. WebTo solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Then, add or subtract the two equations to eliminate one of the variables. mike tyson catalina whale
