We have y=2x and y=x+2
They both equal y, so substitute the first equation for y in the second equation.
2x=x+2
Let’s get x to one side. Let’s subtract x from both sides.
X=2
Since x=2, just plug in 2 for x.
2+2=4
So,
X=2
Y=4

The balanced equation for the given reaction $\mathbf{AgNO_3+NaCl \to AgCl_{(s)} + NaNO_3}$

<h3>What is a double replacement reaction?</h3>

A double replacement is a chemical reaction that takes place in which two reactants swap cations or anions to produce two distinct products.

Whenever the cations representing one of the reactants interact with the anions from another reactant to produce an insoluble ionic compound, a precipitate occurs.

The balanced equation for the given reaction:

$\mathbf{AgNO_3+NaCl \to AgCl_{(s)} + NaNO_3}$
