For -5x+3y+2z=19 the answer is -19/3
You can of course use a calculator, but if you can't, just put them into improper fractions. So 2 3/4 as an example would be 11/4. So if you had 2 3/4 divided by 4 1/2, you'd have (11/4)/(9/2).
When you divide fractions, you can multiply by the reciprocal. So you'd go (11/4)•(2/9)=22/36=
11/18
1. - We need to add fractions
4 6/8 + 3 2/3 = 8 1/2
2. Adding fractions.
8 1/2 + 4 2/4 = 13
3. Once again, adding fractions.
2 4/6 + 5 1/2 = 8 1/6
Those are the answers to 1, 2 and 3!
Please know that these were from my mind, so they may be wrong.
Although, I did my best, and I think they are all right.
Glad I could help, and good luck!
Answer:
