a + b + c + d + e + f + g + h + k + m = 27

a – b + c + d + e + f + g + h + k + m = 23

a + b - c + d + e + f + g + h +k +m = 39

a + b + c - d + e + f + g + h + k + m = -3

a + b + c + d - e + f + g + h + k + m = 21

a + b + c + d + e - f + g + h + k + m = -13

a + b + c + d + e + f - g + h + k + m = -5

a + b + c + d + e + f + g - h + k - m = 11

a + b + c + d + e + f + g + h - k + m = -9

a + b + c + d + e + f + g + h + k - m = 1

a–b+c+d+e+f+g+h+k+m = 23

subtract the equations to get

2b = 4, so

b=2

work with other pairs of equations to evaluate the other variables. Look for a pair which are identical except for the ± sign on one variable.
