Solution

The correct option is B

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, option B is the correct answer.
