Best ResponseYou've already chosen the best response.0Distribute (or multiply) 2 to 3x and 20, eliminating your parentheses. thus you would have... 2x + 6x  40 = 80. Then join your like terms together to make your equation shorter. 2x + 6x and you end up with... 8x  40 = 80 then start to isolate your variable! add 40 to 40 and 80. 8x = 120 now divide 8 to both sides, isolating x! x = 15
