Rearranging equations to solve for a given variable. Equations as important geological tools. Show credits. In an equation, the equals sign acts like the fulcrum of a balance: if you add 5 of something to one side of the balance, you have to add the same amount to the other side to keep the balance...

topic 4 Lesson 4-6/Thursday 11-7-13 Domain: Operations and Algebraic Thinking Objective: Master concepts of 0 less than, 1 less than, and 2 less than when subtracting 0, 1, or 2. Essential Understanding: The number relationships of 0, 1-more-than, and 2-more-than are the basis for addition facts with a 0, 1, and 2.
Dec 09, 2012 · Section 5.4: Solving Multi-Step Equations STEPS FOR SOLVING A LINEAR EQUATION 1. Simplify each side of the equation. Remove parenthesis if necessary. Collect like terms. 2. Add or subtract terms on each side of the equation so that all terms containing the variable are on one side and all constant terms are on the other side. 3.

When multiplying both sides by 4, I will tell students that they may want to write 4 as 4/1 and place any other integer values over 1. Using example 3, they would have 4/1 and -32/1. I think this at least helps students see the "canceling" affect on the variable side of the equation.
To combine them is pretty easy, you just add them together and make sure that they are all on the same side of the equation. First, we will combine all like terms on each side of the equation: Since the 15 and 10 are both constants we combine them to get 25. The 4x and -3x each have the same variable (x), so we can add them to get 1x.
