Answer 2

Given : Different equation:

t=225+9x

x=9+225t

x=225-9t

t=225-9x

To Find : equations represent the balance “x” left in his account after “t” number of days

Solution:

equations represent the balance “x” left in his account after “t” number of days

hence t is independent variable

and x is the dependent variable

x should be isolated

x=9+225t

x=225-9t

are the two equation :

x=9+225t   represent increase in the balance

hence x=x=225-9t  is the required equation

which the balance “x” left in his account after “t” number of days
