Answer:
1.)Originally Answered: What is 3+3x3-3+3=? To do it, you need to multiply 3 by 3 to get 9. Then you add 3 to 9 which gives you 12. Subtract 12 by 3 to get 9 then add 9 by 3 three to get 12, your answer.
Answer:12
2.(First we factor the denominators, then find a common denominator so we can subtract, then cross multiply and solve the resulting polynomial equation.
