Best ResponseYou've already chosen the best response.2Write the equations, one above the other: x + y = 6 x  y = 2 Notice that you have +y in the first equation and y in the second equation. That means that if you add the two equations, the +y and the y will add up to zero and will be eliminated leaving only x in the equation. Let's add the two equations: x + y = 6 x  y = 2  (add equations) 2x = 8 Divide both sides by 2 x = 4 That's all the problem is asking for. Most of the time you need to find y also. Now that we know x = 4, we substitute that value of x in for x in the first original equation: x + y = 6 4 + y = 6 Subtract 4 from both sides: y = 2
