h)-77

i)396

j)297

Answer 2

Let's solve each of these equations step by step:

a) -12 - 57 = -69

b) 11 - 817 = -806

c) 51 - 74 = -23

d) -13 - 174 = -187

e) -13 + 11 - 24 = -26

f) 4 - 15 + 17 - 14 = -8

g) 12 * 5 - 7 * 11 - 102 = 60 - 77 - 102 = -119

h) 5 * (3 - 14) - 9 * 8 = 5 * (-11) - 72 = -55 - 72 = -127

i) 9 * (-5) - (-7) * 4 - (-3) * (-7) = -45 + 28 + 21 = 4

j) 241 - (-2) * 14 + 7 * (-4) = 241 + 28 - 28 = 241

So, the solutions to these equations are:

a) -69 b) -806 c) -23 d) -187 e) -26 f) -8 g) -119 h) -127 i) 4 j) 241
