Answer:
-6n -(3n - 9) + 5n = -4 (2n - 8)
-6n -3n +9 +5n = -8n +32
-9n +5n +9 = -8n +32
-4n + 9 = -8n +32
8n - 4n = 32 - 9
4n = 23
n = 23/4 = 5.75
The first one ,to substitute 3xy from -16 ...so divided both side by 3 .so, (xy =-5.33). the second one,5xy =-20. so,divided both sides by 5 so xy = -4....
