what is X

x= -6

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 3x.

Since 6 is being subtracted from 3x, we add 6 to both sides of the equation to isolate the 3x. On the left, the -6 and +6 cancel out and on the right, -24 + 6 is -18.

So we have 3x = -18.

Now we can finish things off by just dividing both sides of the equation by 3. On the left the 3's cancel and on the right, -18 divided by 3 is -6 so we have x = -6 which is the solution to this equation.

-6

Step-by-step explanation:

3x-6=-24

you add 6 both sides on -6 and -24

you et 3x = -18

you divide both sides by 3

and you get -6

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
