Answer 1

$z - 102 = - 32 + ( - 45) \\ z - 102 = - 32 - 45 \\ z = - 32 - 45 + 102 \\ z = - 77 + 102 \\ z = 25$

$x + 172 = - 78 - 47 \\ x + 172 = - 125 \\ x = - 125 - 172 \\ x = - 297$

$m - ( - 65) = 134 - 200 \\ m + 65 = - 66 \\ m = - 66 - 65 \\ m = - 131$

$x - ( - 67 + 89) = 38 \\ x - ( + 22) = 38 \\ x - 22 = 38 \\ x = 38 + 22 \\ x = 60$

$(x + 43) + 61 = 10 \\ x + 43 + 61 = 10 \\ x + 104 = 10 \\ x = 10 - 104 \\ x = - 94$

$- 12x = 672 \\ x = 672 \div - 12 \\ x = - 56$

$26x = - 494 \\ x = - 494 \div 26 \\ x = - 19$
espero haberte ayudado
