just add the terms together.
you have two of each type of term. treat it just like a normal addition subtraction problem.
(1/8xy - 3/5x³y² + 4.3y³) + (-1/3xy - 3/4x³y² - 2.9y³)
What is the correct answer?
Thank you! :-)

-(27x^(3)y^(2))/(20)+1.4y^(3)+(11xy)/(24)
I got
-(5/24)xy-(27/20)x^3y^3+1.4y^3
Notice that the xy terms are of two DIFFERENT values. 1/8xy-1/3xy=-5/24xy That was your mistake.
-(5/24)xy-(27/20)x^3y^3+1.4y^3
Notice that the xy terms are of two DIFFERENT values. 1/8xy-1/3xy=-5/24xy That was your mistake.
