"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!!!

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
