Answer:
52
Step-by-step explanation:
12-3n=-7n-4(n+5)
Step 1: distribute
12-3n=-7n-4n-20
Step 2: Combine like terms
12-3n=-11n-20
Step 3: Move N to one side
12-3n=-11n-20
+11n +11n
12+8n=-20
Step 4: Get normal numbers to the other side
12+8n=-20
-12 -12
8n=-32
Step 5: Take away the number infront of N by dividing each side by the number of Ns
8n=-32
/8 /8
n= -4
Step 6: Plug N into: 32-5n
32-5(-4)
Step 7: Get rid of parenthesis by multiplying. Negative times Negative is positive.
32+20
Step 8: Finish the problem
Answer is 52
