x = 7, y = 3 satisfies which of the following equations?
x + 3y = 16
The solution of a linear equation must be able to satisfy the equation. The given values of x and y are 7 and 3 respectively.
Among the given equations, only the equation x + 3y is able to satisfy the equation.
⇒7+3(3)=16
Thus, x + 3y = 16 is the correct answer.
