Example #2: Solve the following system using the substitution method 3x + y = 10-4x − 2y = 2 Step 1 You have two equations. Pick either the first equation (top) or the second equation (bottom) and solve for either x or y. I have decided to choose the equation on top (3x + y = 10) and I will solve for y. 3x + y = 10 Subtract 3x from both sides 3x − 3x + y = 10 − 3x y = 10 − 3x Step 2 ...

We are going to use substitution like we did in review example 2 above. Now we have 1 equation and 1 unknown, we can solve this problem as the work below shows. The last step is to again use substitution, in this case we know that x = 1, but in order to find the y value of the solution, we just substitute x = 1 into either equation.
Substitution method can be applied in four steps. Step 1: Solve one of the equations for either x = or y =. Step 2: Substitute the solution from step 1 into the other equation. Step 3: Solve this new equation. Step 4: Solve for the second variable. Example 1: Solve the following system by substitution
The first algebraic approach is called substitution. We will build the concepts of substitution through several examples, then end with a five-step process to solve problems using this method. Example 1. Solve the systems of equations by using substitution: 5 23 x yx We already know x 5, substitute this into the other equation y 2( ) 35
The substitution method is one way of solving systems of equations. To use the substitution method, use one equation to find an expression for one of the variables in terms of the other variable. Then substitute that expression in place of that variable in the second equation. You can then solve this equation as it will now have only one variable.
