Oh, dude, this is like a math riddle, but don't worry, I got you. So, "Twice a number plus 4 is 8" is basically saying 2x + 4 = 8, where x is the mystery number. To solve this, you just subtract 4 from both sides, and you get 2x = 4. Finally, divide by 2, and voilà, the number is 2. Easy peasy lemon squeezy!
Twice a number plus 4 is 8? Honey, that's just a fancy way of saying 2x + 4 = 8 in algebra. To solve this, you just subtract 4 from both sides, giving you 2x = 4. Then divide by 2 on both sides to find x = 2. Voila, you've cracked the code!
3x + (-4) ≥ 2x + 8
Either 2*(n-4) = 2n - 8 or 2n - 4 It depends on whether the "twice" operates on "the number decreased by 4" or "the number".
-8
4+4 =8 8/2 =4 just that you can't see the 8The Real Answer4+4=8 8+4=12 or 4x3=12*multiplying is adding a number to itself however many times*
Let the number be x: 2(2x+4) = 3x+4 4x+8 = 3x+4 4x-3x = 4-8 x = -4
