Answer:
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
