x=3.2
SO from the beginning, you start with the original equation.
to combine like terms(x) you subtract 1.50x from both sides leaving you with 19.00=1.25x+15.00
then to start isolating the variable(x) you subract 15.00 from both sides leaving you with 4.00=1.25x
then with a simple division problem that leaves you with x=3.2
hope I helped!
