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"

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!

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
