Explicación paso a paso:
vertical 1: x - 7/2 = x - 7
x - 7 = 2x - 14
x = 7
horizontal 2: x/2 = x - 10
x = 2x - 20
x = 20
vertical 3: 2x - 18 = 0
2x = 18
x = 9
vertical 4: 3x - 2 = x + 6
2x = 8
x = 4
horizontal 4: 0.01x = 1
x = 100
vertical 5: x + 1 = 3(x + 2) - 7
x + 8 = 3x + 6
2 = 2x
1 = x
vertical 6: x/3 =4
x = 12
horizontal 6: 3(x-2) = 1-(3-x)
3x - 6 = 1 - 3 + x
2x = -2 +6
2x = +4
x = 2
horizontal 7: x + 8 = 2 (16 - x)
x + 8 = 32 - x
2x = 24
x = 12
allí tienes :v
