x=5

`\rightsquigarrow\circ\boldsymbol{Explanation}\circ\leftharpoonup`

To solve for x, we need to first get it all by itself.

`\twoheadrightarrow\sf3x-5=10`

`\bullet` Add 5 to both sides

`\twoheadrightarrow\sf3x=15`

`\bullet` Divide by 3 on both sides

`\twoheadrightarrow\sf x=5`

`\bullet` Great job! We solved for the variable x

Answer 2

`x = 5`

Explanation:

`3x - 5 = 10`

We want to isolate the x.

`3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5`

`3x = 15`

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

`(3x)/(3) \;=\;(15)/(3)`

`x = 5`
