Question

How do you solve `1.04x + 3.14= 7.98`?

Answer 1

`x = 4.65` rounded to the nearest hundredth.

Explanation:

First, subtract 3.14 from each side of the equation to isolate the `x` term and keep the equation balanced:

`1.04x + 3.14 - 3.14 = 7.98 - 3.14`

`1.04x + 0 = 4.84`

`1.04x = 4.84`

Then, divide each side by `1.04` to solve for `x` while keeping the equation balanced:

`(1.04x)/1.04 = 4.84/1.04`

`(cancel(1.04)x)/cancel(1.04) = 4.65`

`x = 4.65` rounded to the nearest hundredth.
