Substitution Method For Solving Systems Of Linear Equations 2 Example 5.2.19. solve the system by substitution. {4x − 3y = 6 15y − 20x = − 30. solution. we need to solve one equation for one variable. we will solve the first equation for x. solve the first equation for x. substitute 3 4y 3 2 for x in the second equation. replace the x with 3 4y 3 2. This algebra 2 math video tutorial explains how to use the substitution method for solving systems of equations containing 2 and 3 variables. this video has.

Solving System Of Equations With 3 Variables Step 5: now, substitute the value of the variable from step 4 in any of the given equations to solve for the other variable. here is an example of solving system of equations by using substitution method: 2x 3 (y 5)=0 and x 4y 2=0. solution: step 1: simplify the first equation to get 2x 3y 15 = 0. now we have two equations as,. Given a system of two linear equations in two variables, we can use the following steps to solve by substitution. step 1. choose an equation and then solve for x or y. (choose the one step equation when possible.) step 2. substitute the expression for x or y in the other equation. step 3. Example 4.2.1. solve by substitution: solution: step 1: solve for either variable in either equation. if you choose the first equation, you can isolate y in one step. 2x y = 7 2x y− 2x = 7− 2x y = − 2x 7. step 2: substitute the expression − 2x 7 for the y variable in the other equation. figure 4.2.1. Use the method of substitution to solve the system of linear equations below. the idea is to pick one of the two given equations and solve for either of the variables, . the result from our first step will be substituted into the other equation. the effect will be a single equation with one variable which can be solved as usual.
