Question

Don’t do 7. And nine it been done already

Answer 1

Answer:

Step-by-step explanation:

8. subtract 78 from both sides so you get r=-93

10. divide both sides by 8 so you get j=12

11. divide both sides by -13 so its z=3

12.divide both sides by 15 so its m=-12

13. divide both sides by 27 to get r=9

14. multiply both sides by 9 (9/1) to get y=-72

15. multiply both sides by 12 to get -j=-96 then divide it by - to get j=96

16. multiply it by 15/1 so its a by itself and then use cross multiplication to simplify it so 4/5 x 15/1 so 15 becomes 3 and 5 becomes 1 so its 4x3 which is 12 so a=12

17. g=6

18. q=4
