    Plug in equation 1 into equation 2 3x + (x+3) = 19 now solve for x

    You can rearrange, using algebra tricks, to manipulate an substitute. That means you can rearrange equation 1: \(\sf \color{red}{y-3 = x}\) notice it says x equals y - 3? well, yeah, thats what it equals to, so substitute THAT thing that x equals to into equation 2: \(\sf \color{blue}{3}(\color{red}{y-3})\color{blue}{+y=19}\)

    right subract 3 from both sides 4x=19-3

    y = x + 3 3x + y =19 plug in the first equation into y 3x + (x + 3) = 19 simplify 3x + x + 3 = 19 4x = 16 divide 4 from both sides. x = 4

    It is simply plug and chug and combining like terms.
