Question

Which equation is equivalent to √x + 11=15

Answer 1

Answer:

Option d is correct

$\sqrt{x}=15-11$ equation is equivalent to √x + 11=15 .

Explanation:

An equation : $\sqrt{x} +11=15$

Subtraction Property of equality states that subtract the same number from both sides of an equation.

For any number a, b, and c

if a =b

then, a-c = b-c

$\sqrt{x} +11=15$

By subtraction property,

subtract the number 11 from both sides of an equation.

$\sqrt{x} +11-11=15-11$

Simplify:

$\sqrt{x}=15-11$

Therefore, the equation which is equivalent to $\sqrt{x} +11=15$ is, $\sqrt{x}=15-11$

Answer 2

√x + 11=15  x=16
√x= 15-11    x=16
