if i factor the expression 7x -89= 9
is 8 x or is it 9?
Nothing to factor
simply solve:
7x -89= 9
7x = 98 <---- I added 89 to both sides
x =14 <---- I divided both sides by 7
Huh ?
What do you mean factor it? Do you have a typo?
7 x - 89 = 9
subtract 9 from both sides maybe?
7 x - 98 = 0
7 (x - 14) = 0
divide both sides by 7
x - 14 = 0
add 14 to both sides
x = 14

==========
7 (14) - 89 = 9 ???
98 - 89 = 9 sure enough
To find the value of x in the expression 7x - 89 = 9, we need to isolate the variable x by applying the steps of algebra.
1. Start by bringing the constant term (-89) over to the other side of the equation by adding 89 to both sides:
7x - 89 + 89 = 9 + 89
7x = 9 + 89
7x = 98
2. Next, to solve for x, divide both sides of the equation by the coefficient (7) of x:
(7x)/7 = 98/7
x = 98/7
So, the value of x is 98/7, which is approximately 14.
Therefore, the answer to the question "is it 8 x or is it 9?" is neither. The value of x in the given equation is 98/7 or approximately 14.
