Solve the equation and check the solution. a minus 2 and one-half = 1 and one-half

a = 1
a = 3 and one-half
a = 4
a = 4 and one-half

a = 4

Step-by-step explanation:

Here, we want to write and solve the given equation

a - 2.5 = 1.5

a = 2.5 + 1.5

a = 4

To check, we simply substitute a = 4

That would be;

4-2.5 = 1.5

This is correct

i think is g(1)=-1.
