Answer:
(-7a-15)/3
Step-by-step explanation:
- 7 = 3/a ( x + 5)
open the bracket
-7 =3/a(x)+ 3/a(5)
-7 = 3x/a+ 15/a
l.c.m is a
-7= 3x+15/a
cross multiply
-7a = 3x+15
-7a-15 = 3x
(-7a-15)/3 = x
Yes. If we multiply 6/13 by 1 in the form of 5/5, we obtain the fraction 30/65 without ever changing the value of the number itself.
