Question

5) Ache qual equações tem conjunto verdade V= {-4}

a) X + 2 = 5 ( )
b) X-1 = 5 ( )
c) X - 7 = 10 ( )
d) x + 1 = 5 ( )
e) Y - 3 = -2 (
f) X + 1 = 3 ( )
g) X - 5 = -9 ( )
h) X-2 = 4 ()

Answer 1

a) X + 2 = 5

x = 5 - 2 = 3

b) X-1 = 5

x = 5 + 1 = 6

c) X - 7 = 10

x = 10 + 7 = 17

d) x + 1 = 5

x = 5 - 1 = 4

e) Y - 3 = -2

y = -2 + 3 = 1

f) X + 1 = 3

x = 3 + 1 = 4

g) X - 5 = -9

x = -9 + 5 = -4

h) X-2 = 4

x = 4 - 2 = 2
