Question

How do you solve `2x - 24= x`?

Answer 1

`x=24`

Explanation:

`"subtract x from both sides of the equation"`

`2x-x-24=cancel(x)cancel(-x)`

`rArrx-24=0`

`"add 24 to both sides"`

`xcancel(-24)cancel(+24)=0+24`

`rArrx=24`

`color(blue)"As a check"`

Substitute this value into the equation and if both sides are equal then it is the solution.

`"left "=(2xx24)-24=48-24=24`

`"right "=24`

`rArrx=24" is the solution"`

Answer 2

`x=24`

Explanation:

We can start by subtracting `x` from both sides to get:

`x-24=0`

Finally, we can add `24` to both sides to get:

`x=24`

Hope this helps!

Answer 3

`x =24`

Explanation:

Bring all the `x` terms to the LHS so minus `x` from both sides

`2x-x-24=color(red)(x-x)`

Bring all the non x terms to the RHS, so add 24 to both sides

`x color(red)(-24+24)=24`

`x =24`
