Twice a number minus two giving us the answer as eight is number 5.
8 doubled is 16. 16 minus 4 is 12. The answer is 8.
970.
Oh, dude, so like, if you have a number, let's call it "x," twice that number would be 2x. Now, if you take 2 away from that, you get 2x - 2. So, 2 less than twice a number is 2x - 2. Easy peasy lemon squeezy!
2(8 + 5) = 2(13) = 26
12-8 = 4 and 2*4 = 8
-18
-6
-6 - (-8) = 2
2 - (-9) - 8 = 3
The answer is -8
-3 - (-8) - (-2) = -3 + 8 +2 = +7
