Combine the like terms to create an equivalent expression: -4q - (-8q) + 10

Like terms are terms that have the same variable and power/exponent.

-4q - (-8q) + 10   (two negative signs cancel each other out and become positive)

-4q + 8q + 10     The only like terms you can combine are -4q and 8q, because they have the same variable of q and an exponent of 1.

4q + 10        (this is as far as you can simplify)

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

if you was gonna solve for a, a is a   < -12
