7.5c-2.5c+8=-7

Combine the like terms:

7.5c-2.5c = 5c

Now you have 5c +8 = -7

Subtract 8 from both sides:

5c = -15

Divide both sides by 5:

c = -15/5

c = -3

Answer:

C = -3

Step-by-step explanation:

To solve this, we need to isolate the c. So we need to subtract 8 on both sides to get :

7.5c-2.5c = -15

Now combining the c's we get:

5c = -15

So c = -3
