Question 159096
-22=11-6a

I guess you are trying to solve for a.

Begin by subtracting 11 from both sides of the equation.

-22 - 11 = -6a

Next, divide both sides of the equation by -6.

-33/-6 = a

33/6 = a

We can reduce this fraction.

Final answer: 11/2 = a

======================

How do we know that the answer is a = 11/2?

We plug the value of [a] back into the original equation given.  If we get the same answer on both sides of the equation, then we will know that the answer is right.

THE PROVE:

-22 = 11 - 6a....This is your original equation.

Replace [a] with (11/2) and simplify.

-22 = 11 - 6(11/2)

-22 = 11 - 3(11)

-22 = 11 - 33

-22 = -22....IT CHECKS!!!

Now we know for sure that a = 11/2

Did you follow?

REMEMBER: Always check your answer.
