Question

quando ta
X-4=3
X+6=5
X-7=-7
X+9=-1
X+28=11
X-109=5
X -39=-79
10=X+8
15=X+20
4=X-10
77=X+8
0=X+12
-3=X+10

Answer 1

a) x - 4 = 3
x = 3 + 4
x = 7

b) x + 6 = 5
x = 5 - 6
x = -1

c) x - 7 = -7
x = -7 + 7
x = 0

d) x + 9 = -1
x = -1 - 9
x = -10

e) x + 28 = 11
x = 11 - 28
x = -17

f) x - 109 = 5
x = 5 + 109
x = 114

g) x - 39 = -79
x = -79 + 39
x = -40

h) 10 = x + 8
10 - 8 = x
x = 2

i) 15 = x + 20
15 - 20 = x
x = -5

j) 4 = x - 10
4 + 10 = x
x = 14

k) 77 = x + 8
77 - 8 = x
x = 69

l) 0 = x + 12
x = -12

m) - 3 = x + 10
-3 - 10 = x
x = -13

Answer 2

X=3+4
X=7

B) x+6=5
X =5-6
X= -1


C) x-7=-7
X= -7-7
X=0

D) x+9=-1
X= -1-9
X= -10

E) x+28=11
X=11-28
X= - 17

F)x-109=5
X=5+109
X=114


G) x-39= -79
X= -79+39
X= -40

H) 10=x+8
-x=+8-10
-x=-2 . (-1)
X= 2


I)15=X +20
-x= + 20 -15
-x= 5 . (-1)
X= -5


J) 4= x-10
-X = -10-4
-x= -14 . (-1)
X=14

K) 77=x+8
-x= 8-77
-x= -69 . (-1)
X= 69


L) 0=x+12
-x=12-0
-x=12 . (-1)
X= -12

M) -3=x+10
-x=10+3
-x=13 . (-1)
X= -13
