Answer:
c = -10
Step-by-step explanation:
16c -24=4c -144
Subtract 4c from both sides
16c - 4c - 24 = 4c - 4c - 144
12c - 24 = -144
Add 24 to both sides
12c -24 + 24 = -144 + 24
12c = -120
Note: -144 + 24 = -120
12c = -120
Divide both sides by 12
12c/12 = -120/12
c = -10
Note: 12/12 = 1 and -120/12 = -10
Checking :
16c -24=4c -144
Put c = -10
16(-10) - 24 = 4(-10) - 144
-160 - 24 = -40 - 144
-184 = -184
Therefore
c = -10
