| P. x = 15 is the solution of the equation\[41-x=25\]. |
| Q. An equation is an algebraic expression which involves an "equal to" sign. |
| R. 'x exceeds y by 7' can be expressed as\[x=y+7\]. |
A)
P Q R F T T
B)
P Q R F T F
C)
P Q R T F T
D)
P Q R T T T
Correct Answer: A
Solution :
(P) \[41-x=25\Rightarrow 41-x-41=25-41\] \[\Rightarrow -x=-16\] [Multiplying both sides by (-1)] \[\Rightarrow -(-x)=-(-16)\Rightarrow x=16\]
