10/2= a/a-9

10/2=a/a+-9

Multiply all terms by a and cancel

10a/2 = a+-9a

Simplify both sides of the equation

5a= -8a

Add 8a to both sides

5a+8a= -8a+8a

13a=0

Divide both sides by 13

13a/13=0/13

a= 0

Answer : No solution


I hope that's help !

for this question you can say:
10/2 = a/a-9 is equal to 2a = 10a - 90
so now you should add -10a on both sides:
2a -10a = -90 ⇒ -8a = -90 ⇒ a = -90/-8 ⇒ a = 11.25 :)))
i hope this is helpful
have a nice day
