x=-4

Step-by-step explanation:

x +9 -4 = 1 first combine like terms on the the left side to get

x + 5 = 1 now subtract 5 from both sides

-5 -5

x= -4

The required solution is x = 21.

Step-by-step explanation: We are given to solve the following equation for x :

"Square root of x minus 5 + 7 = 11."

The given equation can be written and solved as follows :

Thus, the required solution is x = 21.

√x + 9 - 4 = 1.

√x + 5 = 1

Subtract five from both sides of the equation: √x = -4

x = -16.

Check: -√16 + 9 - 4 = 1

1 = 1

√x + 5 = 1

Subtract five from both sides of the equation: √x = -4

x = -16.

Check: -√16 + 9 - 4 = 1

1 = 1

√x + 5 = 1

Subtract five from both sides of the equation: √x = -4

x = -16.

Check: -√16 + 9 - 4 = 1

1 = 1
