How do you solve two-step equations?
1 Answer
Explanation below!
Explanation:
It takes two steps to solve an equation that has more than one operation:
-
Simplify using the inverse of addition or subtraction.
-
Simplify further by using the inverse of multiplication or division.
Let's have an example equation.
The first step is to add twelve to both sides, since addition is the inverse operation of subtraction, to remove negative twelve from left hand side.
Why are we doing this?
Beacause we want to achieve
Now since two is being multiplied with the variable
We don't have to care about the right hand side, if it is a fraction or a decimal. All we care about is our variable, which must be isolated on the left hand side of the equation.
That's it!
