The answer is 160. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
3 + 11 + 11 + 11 + 12 + 13 + 15 + 15 + 16 + 17 + 19 = 143
17 + 14 + 17 + 19 + 18 + 13 + 11 = 109
8 plus 1 times 12 minus 13 is equal to seven.
It's impossible for that to happen. 6 plus 7 is 13, not 12.
-8 + 19 = 11
3 + 11 + 11 + 11 + 12 + 13 + 15 + 15 + 16 + 17 + 19 = 143

-11+x = 13-x TAKE x FROM BOTH SIDES -11 = 13-2x TAKE 13 FROM BOTH SIDES -24 = -2x DIVIDE BY TWO ON BOTH SIDES -12 = -x x = 12
17 + 14 + 17 + 19 + 18 + 13 + 11 = 109
8 plus 1 times 12 minus 13 is equal to seven.
13/13 + 12/14 = 13/7 or 16/7
It's impossible for that to happen. 6 plus 7 is 13, not 12.
-8 + 19 = 11

11 plus 12 plus 13 can satisfy this
yes! 11+2=13 12+1=13
