ANSWER

The correct answer is option B

EXPLANATION

The equations are

$3x+5y=29---(1)$

and

$x+4y=16---(2)$

When we multiply the second equation by $-3$ , we obtain;

$-3x-12y=-48---(3)$

When we combine this new equation with equation (1).

$-7y=-19$

We can see that $x$ has been eliminated from the equation.

We can then, solve for $y$ and then substitute the result in to any of the equations to find $x$ .

Hence the correct answer is option B
