Ecuación 1
28 + 25 + x = 180
53 + x = 180
x = 180 - 53
∴ x = 127
Ecuación 2
x = 65 + 70
∴ x = 135
Ecuación 3
3x - 10 = 8x - 50
- 10 + 50 = 8x - 3x
40 = 5x
40/5 = x
8 = x
∴ x = 8
Ecuación 4
5x + 20 = 7x - 80
20 + 80 = 7x - 5x
100 = 2x
100/2 = x
50 = x
∴ x = 50
Ecuación 5
x + 62 = 180
x = 180 - 62
∴ x = 118
Ecuación 6
52 + x = 360
x = 360 - 52
∴ x = 308
Ecuación 7
85 = 60 + x
85 - 60 = x
25 = x
∴ x = 25
