3 Ways to Solve Multivariable Linear Equations in Algebra

NettetLinear equations with two variables are equations that have two variables that are not raised to any power. An example of an equation with two variables is x +2 y =5. … NettetProvided you have N distinct equations, you can always solve for N variables. I say distinct because these two are not: 7a + 2b = 50 14a + 4b = 100 They are the same equation multiplied by two so you cannot get a solution from them - multiplying the first by two then subtracting leaves you with the true but useless statement: 0 = 0 + 0 NettetNotice how the second equation changes with the substitution we performed above! Our two variable equation 2𝑥𝑥+ 2𝑦𝑦= −6 just became the one variable equation 2𝑥𝑥+ 2(2𝑥𝑥+ 3) = −6. And we know how to solve one variable equations. 2𝑥𝑥+ 2(2𝑥𝑥+ 3) = … 78栄伸号
