Question

What number needs to be eliminated to solve this equation? -8/X=72

Answer 1

8x9 so, 8

Answer 2

no go away

Answer 3

first cross multiply which gives you -8 = 72x now divide both sides by 72 which gives you x = -1/9

Answer 4

-(8)/x=(8)9 cancel 8. -1/x=9 multiply both sides by x -1(x)/x=9x x cancel divide by nine x=-1/9. By using this way you eliminate a number before multiplying like good mathematicians do.
