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.
Answer:
9x = 52
Step-by-step explanation:
Brandon + Michael = 2 + 7 friends = 9
x= number of cards each player receives
Solve it by simply dividing 52 by 9 which gives you x = 5.78
So there would be only enough cards for each player to have 5. Then 7 left over.
