Question

Which of the following is not true?  A ) x + 10 = -12 ; x = 22 B ) 5y = - 25 ; y = -5 C ) x - 29 = 18 ; x = 47 D ) p / 7 = 4 ; p = 28​

Answer 1

Answer:

A) The statement is not true

Step-by-step explanation:

Given :-

A ) x + 10 = -12 ; x = 22

B ) 5y = - 25 ; y = -5

C ) x - 29 = 18 ; x = 47

D ) p / 7 = 4 ; p = 28

To find:-

Which of the following is not true?

Solution :-

A) Given equation is x+10 = -12

=> x = -12-10

=> x = -22

The value of x = -22

B) Given equation is 5y = -25

=> y = -25/5

=> y = -5

The value of y = -5

C) Given equation is x-29 = 18

=> x = 18+29

=> x = 47

The value of x = 47

D) Given equation is p/7 = 4

=> p = 4×7

=> p = 28

The value of p = 28

Answers:-

A) The statement is not true

B) The statement is true

C) The statement is true

D) The statement is true
