LAST QUESTION PLEASE HELP
Amanda tells you that when variables are in the denominator, the equation becomes unsolvable. "There is a value for x that makes the denominator zero, and you can't divide by zero," Amanda explains. Using complete sentences, demonstrate to Amanda how the equation is still solvable. please help!!!

Answer 1

Let's suppose the equation is
1/(x-7) = 21

When x = 7 the equation is unsolvable because of the zero denominator.
However, the equation is still solvable because x does not equal 7.
1/(x-7) = 21

1 = 21x -147
21x = 148
x = 148/21
x = 7.0476190476

Answer 2

okay
