Question

Solve for all possible values of x. square root of the quantity x plus 7 end quantity minus 11 equals 2

x = 6
x = 20
x = 162
x = 169

Answer 1

the value of x=162

Explanation:

square root of the quantity x plus 7 end quantity minus 11 equals 2

`√(x+7) -11=2`

Add 11 on both sides

`√(x+7)=13`

To remove square root, take square on both sides

`x+7=169`

To get x alone, subtract 7 from both sides

x=162
