so if i have the equation (4/3a)+[3/(3a+1)]=-2 should my LCD be 3a(3a+1) or just 3a+1? if so how would I multiply it out?

okay then I just cancel out factors? like the (3a+1) in the numerator and denominator in the first part?

okay i got thus far: 7/(3a)(3a+1)=-6a/(3a) how would I solve for a though?
