See each answer below.
1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.
2) Dividing by 3 and taking the square root gives an answer of 0.
3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.
4) Divide by 4 and then take the square root. You have positive or negative 5/2.
