Solving Equations Amongst Variables On Both Sides Of The Equal Sign

After solving equations amongst variables on 1 side of the equal sign, it's fourth dimension to create variables on BOTH sides of the equal sign.

For this topic, I made a booklet foldable amongst ii give-and-take occupation practise problems inside.

Outside of foldable amongst steps:

Inside:

Every twelvemonth when nosotros are reviewing for the EOI exam, my students become hung upwards on this released attempt out question:

Usually, in 1 lawsuit I assistance them ready the revenue = costs equation, they tin flame figure it out. I decided to write some of my ain practise problems virtually this as well as stick them inwards this unit of measurement as well as hence students could get-go getting used to this kind of problem.

For the ii problems I wrote to brand sense, there's a few facts yous convey to know.

1. Drumright, the town I alive inwards as well as instruct in, is a sometime fossil oil boomtown. We similar to theme everything roughly oil. Our yearly festival is called Oil Patch. Our paper is called the Gusher. We convey a motel inwards town called the Boomtown Inn.

2. I taught this lesson on the Mon AFTER Oil Patch. I'm constituent of the Friends of the Library organization, as well as our fundraiser at the festival was to sell bookmarks designed past times local uncomplicated schoolhouse students as well as cotton fiber candy. (Except the cotton fiber candy machine wasn't working properly as well as hence I but ended upwards selling bookmarks...)

Last Year's Oil Patch Setup

3. Booth Rental is $50. I but made upwards all the other numbers. Don't worry. I told my students this, too.

I similar that students had to write their ain costs as well as revenue equations earlier existence able to motility forward. This made the enquiry of fifty-fifty a higher grade of difficulty than what volition move expected on the EOI.

I actually liked it when 1 pupil suggested that I would postulate to sell 50 bags of cotton fiber candy to interruption even. This sparked a ground amongst other students inwards the class who pointed out yous also had to pay for supplies for the cotton fiber candy yous sell!

After working through these ii give-and-take problems, I gave my students some to a greater extent than traditional practise problems amongst variables on both sides of the equal sign.

And, but similar amongst solving equations amongst variables on 1 side of the equal sign, I had students utilization the estimator to banking enterprise check the solutions they found.

They all the same used the calculator's shop function, but they had to come inwards both sides of the equation as well as run into if the answers matched.
