Using Substitution to Solve Systems of Equations Activity. Directions Match the system of equations with the modified equation that can be used to solve the system of equations by substitution. Draw a line between the system and the equation used to substitute. 2x + y = 11. x – y = 2 x = -2y + 6. 4x – y = 7. 5x – 8y = 2 x = -6y + 5

Use substitution to solve the system of equations. If the system does not have one solution tell whether it has infinitely many solutions or no solution. Y = 2x + 1. Y = 2x + 2 (* You may have a prediction about the answer based on the slopes of the equations ( ) Step 1 – Choose either equation and solve for a single variable.

There are two ways to solve a system of equations (algebraically and graphically). We will focus on solving algebraically. There are two methods of solving algebraically (substitution and elimination). The key to both of them is changing one (or both) equations so there is only one variable to solve for.

The solution to the system of equations is (1, -2). 15. Use substitution to solve the following system of equations: 3x + 4y = -1. 6x – 2y = 3. Solve for x in the first equation. Show your work. Substitute the value you got for x into the second equation, rewrite the equation, and solve for y. (Hint: Remember to use parentheses.) Show your work.
