Question

What number needs to be eliminated to solve this equation? −8/x=72

a) x=−1/9
b) x=−9
c) x=−72
d) x=8

Answer 1

To solve the equation -8/x = 72, multiply both sides by x, then isolate x by dividing both sides by 72 to get a) x = -1/9.

Step-by-step explanation:

To solve the equation -8/x = 72, we need to eliminate the value of x in the denominator. We can do this by multiplying both sides of the equation by x.

This gives us -8 = 72x. To isolate x, we divide both sides of the equation by 72. So, x = -8/72. Simplifying further, x = -1/9.

Therefore, the number that needs to be eliminated to solve the equation is x = -1/9, option a).
