Question

How do you solve `2x = 12`?

Answer 1

`x=6`

Another way of looking at it!

Explanation:

The you need to get one `x` on its own on one side of = and everything else on the other side.

This is how you do it for your question:

When multiplying, change what you want to get rid of into 1 as anything multiplied by 1 does not change.

`color(blue)("Method for getting rid of the 2 on the left.")`

Divide both sides by 2

`color(brown)(2x) -: 2=color(brown)(12) -:2`

`color(green)("If you divide one side of = by any number you have to")`
`color(green)("divide the other side by the same number")`

Write as: `2/2 xx x=12/2`

but `2/2` is 1

`1xxx=6`

`x=6`
