X^2/(x- 9 = 81/(x - 9)
This is the equation for which you want the solution.
Multiplying both sides of the equation by (x - 9) we get
x^2(x - 9)/(x - 9) = 81(x - 9)/(x - 9)
So the (x - 9) goes out from both the denominator and the numerator and then the simplified equation becomes
x^2 = 81
x ^2 = (9)^2
x = 9
So the value of the unknown variable x comes out to be 9.
First, fill in the variables with the numbers given so that
2b-3c
will then become
2(4)-3(2)
next, you refer to the order of operations to simplify the problem down, the multiplication being the first doable operations in this problem.
8-6
and next operation being subtraction.
2
is the final answer
Answer:

Step-by-step explanation:
divide 2 into 40 that gives you 20 then subtract 2 that gives you your answer
cause she only had two left
Answer:
a=2/23
Step-by-step explanation:
-53a-16a+18-12=0
-69a+6=0
-69a=-6
-69a/-69=-6/-69
a=2/23
