Answer:
-(23)/(4) or 5.75

Explanation:

Step 1. Simplify 21 + 30 to 51

51 = −4c + 28

Step 2. Subtract 28 from both sides

51 - 28 = -4c

Step 3. Simplify 51 - 28 to 23

23 = -4c

Step 4. Divide both sides by -4


-(23)/(4) = c

Step 5. Switch sides

c =
-(23)/(4)

Decimal Form Answer: -5.75

I hope this helps you out.

Answer:

-23/4 =c

Explanation:

21+30=-4c+28​

Combine like terms

51 = -4c+28

Subtract 28 from each side

51 = -4c+28

Subtract 28 from each side

51-28 = -4c+28-28

23 = -4c

Divide each side by -4

23/-4 = -4c/-4

-23/4 =c
