-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.
