#### Learn about linear **equations** using our free math **solver** with step-by-step solutions.**Guided** Practice: Steps for **Solving Systems of Equations by Substitution** 1. (If necessary) Manipulate one of the **equations** to isolate a variable (**if you're isolating the y-variable, you will be converting your equation to slope-intercept form). 2. Rewrite the equation substituting the equivalent values. Students will be placed in groups of three and determine which method of **solving systems** of linear **equations** works well with the problem given. Students will review a problem **solving systems** of linear inequalities. Day 5 . Quiz. Topics will include: **Solving systems** of Linear >**Equations**</b> using <b>**Substitution**</b>, Elimination and Graphing Methods. Step 2: Substitute the expression from Step 1 into the OTHER **equation**. • The resulting **equation** should have only one variable, not both x and y. Step 3: Solve the new **equation**. • This will give you one of the coordinates. Step 4: Substitute the result from Step 3 into either of the original **equations**. Step 5: Solve for the other coordinate.
