Question

How do you solve `0.06x + 0.24 - 0.02x = 0.36`?

Answer 1

The solution is `x=3`.

Explanation:

Bring all the quantities with x on one side of the `=` and the others on the other side remembering that the "jump" of the `=` changes the sign.

`0.06x+0.24-0.02x=0.36`
`0.06x-0.02x=0.36-0.24`

Now, on the left side we sum the numbers in front of the `x` and on the right we sum the numbers.

`(0.06-0.02)x=0.36-0.24`

`0.04x=0.12`

Finally we divide both sides for the number in front of `x` in order to cancel it and leave the `x` alone

`0.04/0.04x=0.12/0.04`
`x=0.12/0.04`
`x=3`.
