Answer:
Step-by-step explanation:
(-3/9 + 4/3)+ a = 0
first solve our terms in the parentheses by adding them
to do this we have to find the lcd ( lowest common denominator)
9 works for both so I multiply both halves of 4/3 by 3 to get my denominator to 9 the other fraction is already at a denominator of 9 so we leave it alone
(-3/9 + 12/9)+ a=0
then add
(9/9)
9/9=1 SO WE SIMPLIFY
1+a=0
now we isolate our variable (a) to do this we subtract 1 from both sides of our equals sign to get the answer
a=-1
hope this helps
