Question

encuentra el valor de la incognita en cada caso
104+a =-45
-94 = m - 46
x +24 = - 18
x + 36 + 3 x = 100
m - 14 = - 17 + 38
x - 78 + 34 = 96
7b - 116 = - 4
- 37 + m = - 89

Answer 1

104 + a = -45
a = -45 - 104
a = -149

-94 = m - 46
-94 + 46 = m
- 48 = m

x + 24 = -18
x = -18 - 24
x = -42

x +3 6 +3x = 100
4x = 100 - 36
4x = 64
x = 16

m - 14 = -17 + 38
m = 21 + 14
m = 35

x - 78 +34 = 96
x - 44 = 96
x = 96 + 44
x = 140

7b - 116 = -4
7b = -4 + 116
7b = 112
b = 16

-37 + m = -89
m = -89 + 37
m = - 52
