Example Question #91 :Solve Real World And Mathematical Problems By Writing And Solving Equations: Ccss.Math.Content.6.Ee.B.7

Solve for:

Possible Answers:

Correct answer:

解释:

The equationasks us to identify which number,, multiplied byis equal to.

In order to solve this equation, we need to isolate thevariable on one side of the equals sign. We will do this by performing the opposite of the operations that were done on the variable,. We need to remember that whatever we do to one side of the equals sign, we have to do to the other.

Sincewas multiplied by the variable, we can dividefrom both sides of the equation.

我们可以检查麦e sure we have the correct value forby plugginginto the original equation; thus:
