Question 64039: I am a parent trying to help my daughter with this equation. I am not sure what I am doing incorrectly.
-4=7x-(-1)/8 Found 2 solutions by sarahschober, praseenakos@yahoo.com:Answer by sarahschober(35) (Show Source):
Add (-1)/8 on both sides of the equation.( Because here we want to find the value of x. For that bring all the x terms in one side and all the other terms into other.)
Here in the right side we have (-1)/8 is subtracting from 7x, so add both sides by that term so that it will get cacelled from the right side and only 7x will retain.
==> -4 +(-1)/8 =7x-(-1)/8 + (-1)/8
==> -4 +(-1)/8 = 7x --------------------------(1)
Now we have to simplify the left hand side.
Here we can rewrite the expressions as follows,
-4/1 +(-1)/8
Here the denominators are not same so first of all make it equal.
Find out the least common factor of 1 and 8, which is 8
Multiply whole term by 8 and put tha common denominator 8
