4 Storing

4.1 Storing a solution value

You can use the store feature of the calculator to rename a letter or variable

as a speciﬁc value. This is especially helpful when a value is complex or

contains non-terminating digits.

Example 6. Given the equation 0.4x = 0.2(0.6x) − 4 we solve for x to

ﬁnd a solution as x = −

100

. Upon approximating u this solution as a

decimal we have x ≈ −14.285 . . .. If we were to check our solution by plugging

the approximate solution x ≈ −14.285 . . . into the original equation, our

solution would only check approximately. Instead we can store the exact value

x = −

100

and expect our solution to check exactly. To store the value −

100

into x we can retype our solution in the next line or you may use the button

marked D for the most recent answer. The correct format to store a value

into a variable is always value FIRST then W, chosen italic variable then

E button.

If I choose the variable x it will remain the value −

100

until otherwise

stored or cleared. To check our solution we wish to show that the left hand

side is equal to the right hand side.
