Two-step equations are those that require two steps in the process to work out the answer. For example, 2u-1=3 is a two-step equation. To solve it, you would take a first step of adding one to both sides to make it 2u=4. Your second step would then see you divide both sides b...

If you have a multiplication you need to move, you can undo that multiplication with a division—on both sides of the equation. Head First: Ok, I think I get it—you can move numbers from one side of the equation to the other. So you’re pretty useful for getting a variable by ...
Basic Equation Solving 1) in solving eq., our goal is to find the unknown value of the variable 2) mathematically, it is always legal to do any arithmetic operation to both sides of an eq. 3) strategically, we undo the order of operations to isolate the variable ...
Recall that a single linear equation in two variables is an equation of the form Ax + By = C, where A and B are both nonzero real constants. There are infinitely may ordered pairs that satisfy a single linear equation. In applications however, we are often interested in finding a single...
Solving Equations With Variables on Both Sides If you have any fractions, get rid of those first by multiplying ALL terms by the denominator. Use the distributive property if needed. Your ultimate goal is to get all of the constants on one side of the equation and all of the variables on...
Our findings suggest that the teachers see this conception of equation as useful for equations in one variable. They struggle with its ramifications for equations in two variables. Nonetheless, this conception of equation leads them to reflect on the algebra curriculum in substantial ways; two of ...
Linear equations in one variable can be used to calculate the value of an integer when we are given two or more integers with one of them being unknown. Using the expression in an equation form, we can easily find the value of an unknown integer. Linear equation helps us deduce integers ...
