Step-by-step explanation:
=3a+a-36+4a
=4a+4a-36
=8a-36
=4(2a-9)
Because 5/15 is not a simplified fraction, seeing that its numerator and denominator both have a common factor, you can simplify it to find an equivalent fraction. To do this, divide 5 from the numerator and denominator and then you would get a result of 1/3.
