First thing we are going to do to solve this is to subtract 1.5 from both sides so:
5x+1.5−1.5=7−1.5
5x=5.5
Next we are going to divide from both sides by 5 so:
5x/5=5.5/5
Finally your final answer shall be:
x=1.1

I hope this helps!
5x+1.5=7
     -1.5  -1.5
    --------------
5x     =   5.5
----        ------
5               5

x = 1.1

subtract 1.5 from both sides, then with that answer, you divide it by 5.
x = 1.1
