this week in math we learned about systems in linear equations. A system in a linear equation is where 2 lines meet. You can solve this by taking the 2 equations, x + 2 = y and 3x + 4y = 1. you need to get a variable by its self on one side of the equation like y in x + 2 = y. Now, you have to put the x + 2 into the other equation in place of the y so you would get 3x + 4(x + 2) = 1 and then expand it to get 3x + 4x + 8 = 1 and add the like terms  but put the numbers without a variable to the other side of the equation to get 7x = -7 and now divide to get x = -1. To get the y you need to add the x into one of the equations (the first one is easier) to get -1 + 2 = y and solve to get y = 1.
