12x-6=9x

• algebra -

12x-6=9x

12x - 9x = 6

3x = 6
x = ?

• algebra -

12x - 6 = 9x

Subtract 9x from both sides.

3x -6 = 0

3x = 6

I assume you can carry on from there.

• algebra -

12x6=9x8

• algebra -

12x-6=9x

first step: subtract x-variables to one-side of the equation

-6=-3x

second step: divide -3 to the other side to get the value of x

Lastly, you can check your answer of x=2 by plugging it into the original equation to see if both sides of the equation are equal.

12(2)-6=9(2)
18=18
Therefore x=2 is correct

• algebra -

x=2
