Question:-
is x = 8 a solution to the equation x + 7 = 15
A yes, because 8+7 is not true.
B yes, because 8+7 = 15 is true
C no, because 8+7=15 is true
D no, because 8+7=15 is not true

Explanation:-
=> x + 7 = 15
=> x = 15-7
=> x = 8
-------------------------------------------------------
We know that 8+7 equals to 15.
Therefore , x = 8 is the solution of the equation x+7 = 15
