How to Solve Systems of Algebraic Equations Containing …

WebAny system of equations can be solved in different methods. To solve a system of equations in 2 variables, we need at least 2 equations. Similarly, for solving a system of equations in 3 variables, we will require at least 3 equations. Let us understand 3 ways to solve a system of equations given the equations are linear equations in two variables. WebFor the cross-multiplication method for solving 2 variable equation, the formula used is: x / (b1 c2 − b2 c1) = y / (c1 a2 − c2 a1) = 1 / (b2 a1 − b1 a2) For example, consider the equations 2x + 3y = 9 ———– (i) And, x – y = 3 ———– (ii) Here, a 1 = 2, b 1 = 3, c 1 = -9 a 2 = 1, b 2 = -1, c 2 = -3 Now, solve using the aforementioned formula. china moon howell menu
