If - 3x = - 18, what is the value of x?

-3x=-18

divide both sides by - 3

to get + x

to get x by itself

-3x/-3=-18/-3

cross out - 3 and - 3, divide by - 3

then becomes - 1*-1*x=1*x=x

x=-18/-3

answer:

x=6

Answer: x = 6

Step-by-step explanation: To solve for x in this equation, we want to get x by itself on the left side of the equation. Since x is being multiplied by - 3, to get x by itself, we need to divide by - 3 on the left side of the equation. Since we divided by - 3 on the left side, we must also divide by - 3 on the right side.

On the left side, notice that the - 3's cancel out so we are simply left with x. On the right side, we have - 18 : - 3 which is 6 so we have x = 6.

Finally, remember to check your answer by substituting a 6 back into the original equation. So we have - 3 (6) = - 18 which is a true statement.

So our answer x = 6 is correct.

Remember to show all your work when solving equations.
