You can
put this solution on YOUR website! I am trying to help my daughter
and it has ben 27 years since i had algebra.
my questin is on solving equations and formulas.
If i could get a small refresher on how to do
this i may can remember how to explain this to
her. the problem is:
16z + 4x = y for x
If i could get a detailed walk through i can help her.
thank you.
16z + 4x = y
Get rid of all terms on the left which do not contain x
by adding their opposite to both sides. We want to get
rid of the 16z on the left so we will add -16z to both
sides. So put -16z under both sides. Put the -16z under
the 16z. On the right side put the -16z beyond the last
term because there is no term in z on the right side:
16z + 4x = y
-16z -16z
-----------------------
Now add vertically term by term:
16z + 4x = y
-16z -16z
-----------------------
4x = y - 15z
Now we get rid of the coefficient of x, which is 4, by
dividing both sides by 4:
16z + 4x = y
-16z -16z
-----------------------
4x = y - 15z
4x y - 15z
---- = ---------
4 4
Now we can cancel the 4's on the left,
1
4x y - 15z
---- = ---------
4 4
1
y - 15z
x = ---------
4
