Question

Which equation is equivalent to √x + 11=15

a x + 11 = 225

b x + 121 = 225

c √x=15+11

d √x=15-11

Answer 1

√x + 11=15 x=16
√x= 15-11 x=16
Answer is D

Answer 2

Option d is correct

`√(x)=15-11` equation is equivalent to √x + 11=15 .

Step-by-step explanation:

An equation :
`√(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

`√(x) +11=15`

By subtraction property,

subtract the number 11 from both sides of an equation.

`√(x) +11-11=15-11`

Simplify:

`√(x)=15-11`

Therefore, the equation which is equivalent to
`√(x) +11=15` is,
`√(x)=15-11`
