Aubrey is using the substitution method to solve the following system of equations y − x = 21 2y = 2x 16 She arrives at an answer of 8 = 21 She thinks that this answer means that the lines are parallel and that the system has no solution.  Substitution Method – Example Study the example below that shows how to use the substitution method in systems of equations Example Solve for x and y if 3x 2y = 4 and x 4y = 3 Answer x = 1 and y = 1/2 Step 1 Label the equations Label the equations A and B (A) 3x 2y = 4 (B) x 4y = 3 Step 2 Isolate one of the variables. 1) So the solution to the system of simultaneous equations is x = 2 and y = 1 We can also check the solution using algebraic methods Substitute equation ( 1) into ( 2) x = 2 y ∴ y = 2 ( 2 y) − 3 Then solve for y y − 4 y = − 3 − 3 y = − 3 ∴ y = 1.

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 $$ y = 2x 1 \\ y = 2\cdot \red{1} 1 = 2 1 =3 \\ \\ \boxed{ \text{ or you use the other equation}} \\ y = 4x 1 \\ y = 4\cdot \red{1} 1 \\ y = 4 1 = 3 \\ \boxed { ( 1,3) } $$. Since we want to solve with substitution, we must solve for one variable in one of the equations I think it would be easiest to solve for y in the first equation y = 5 −2x We can now substitute into the other equation 3x 2(5 − 2x) = 9 3x 10 − 4x = 9 −x =.

Step 4 Back substitute Once a value is found for a variable, substitute it back into one of the original equations, or their equivalent equations, to determine the corresponding value of the other variable to find the value of the other coordinate Substitute x = 1 into either of the original equations or their equivalents Typically, we use the equivalent equation that we found when.

The elimination method for solving systems of linear equations uses the addition property of equality You can add the same value to each side of an equation So if you have a system x – 6 = −6 and x y = 8, you can add x y to the left side of the first equation and add 8 to the right side of the equation And since x y = 8, you are adding the same value to each side of the first. The given pair of equation are `x/2 y = 08 =>x 2y = 16(a)` `7/(x y/2) = 10 =>7 = 10(x y/2) => 7 = 10x 5y`.  Solving Systems Of Equations By Substitution Method In this method, we first find the value of one variable (y) in terms of another variable (x) from one equation Substitute this value of y in the second equation Second equation becomes a linear equation in x only and it can be solved for x Putting the.
