35 = - 5/9x
mutiply both sides by -9/5
35*-9/5= -5/9x*-9/5
Cross out 5 and 35, divide by 5.
35/5= 7
-5/5= -1
Cross out the 5 and 5 , divide by 5.
Cross out the 9 and 9, divide by 9.
then becomes 1*1*x= x
7*-9= -63
Answer : x= -63

Answer:
Excluded values are 3 and -4
Step-by-step explanation:
To simplify the expression multiply to create a common denominator.
Multiply the first fraction by (x-3) and the second fraction by (x+4).
Excluded values are values which make the denominator 0. This means (x-3)(x+4) cannot be 0. This means x cannot be 3 or -4. These are excluded values.
