WebBy using the substitution method of solving linear equations, let us take the first equation and find the value of 'y' and substitute it in the second equation. From equation (1), y = 13-3x. Now, substituting the value of 'y' in equation (2), we get, 2x + 3 (13 - 3x) = 18 2x + 39 - 9x = 18-7x + 39 = 18-7x = 18 - 39 WebJan 6, 2024 · Substitution works well when we can easily solve one equation for one of the variables and not have too many fractions in the resulting expression. The third method of solving systems of linear equations is called the Elimination Method.
WebJan 10, 2024 · Substitution Method: This method involves isolating for one variable (x/y) of Line 1 then substituting that variable into Line 2. This will allow you to isolate and solve for the other variable (y/x). Once you have the x- and y- coordinates, you then have the solution which is the point of intersection between the two lines. Line 1: y = 6 ... WebExample #2: Solve the following system using the substitution method 3x + y = 10-4x − 2y = 2 Step 1 You have two equations.
