1)  9x + 2 = x + 5  ---> 9x + 2 = 6

subtracted X from one side but not the other

2) 3(x-4) + 5 = 12  ---> 3x + 4 + 5 = 12

didn't distribute correctly: 3(x-4)

multiplied the X by 3 but not the -4

16c-24=4c-144<br><br> can you please explain how to do this equation
love history [14]

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

I hope this was helpful, please rate as brainliest
