Easy to understand explanations on solving two-step algebra equations. Now that you know all the rules for solving one-step equations, solving two-step algebra equations will be a piece of cake!
Look for and express regularity in repeated reasoning. Launch 10 minutes Two-Step Equations Opener: As students enter the room, they will immediately pick up and begin working on the opener — Instructional Strategy - Process for openers.
This method of working and going over the opener lends itself to allow students to construct viable arguments and critique the reasoning of others, which is mathematical practice 3. Two Step Equations Explore Narrative This lesson builds on what students have previously learned regarding one-step equations.
Students will take what they learn one step further by having to perform two inverse operations. Students will be asked to persevere with problems mathematical practice 1 and pay close attention to those steps and signs mathematical practice 6.
The biggest problem I run into with this lesson is students using the wrong sign when performing inverse operations - for example if you have 2x - 5, students will want to subtract 5.
I tell struggling students to circle their terms, which include the sign right in front of them. That usually helps with the sign issue!©8 f2P0 B1V2M 7K Uu Otpa3 gS xolfetEw Ja 3r2e k RLzLUCx.

The main difference between one-step equationsand two-step equations is that one more step you need to do in order to solve a two-step equation. That additional step may be something like multiplying the variable by a certain number to get rid of a fraction in front of it.
Otherwise, the rules are the same as before and these equations are just as easy to learn and solve as are the one-step ones. Improve your math knowledge with free questions in "Solve two-step equations" and thousands of other math skills.
Step One: State the issue. Step Two: Identify the rule, but don't waste time stating the rule. 2 Step Three: Summarize the elements of the rule that are easily satisfied by the facts.
Practice writing equations to model and solve real-world situations. Solve the equation. The examples done in this lesson will be linear equations. Solutions will be shown, but may not be as detailed as you would like.
