Best ResponseYou've already chosen the best response.0Use the substitution method and isolate x in the first equation. x + 3y = 1 x + 3y  3y = 1  3y x = 1  3y After you've isolated x, plug in what x equals onto the second equation. 2x + 2y = 6 2(1  3y) + 2y = 6 Distribute the expression in parenthesis. Next, combine all like terms and solve for y. If you've received y, just plug it back in the first original equation to receive the value of x. That will be your (x, y) value, or your solution.
