Answer 1

a) × + 5 = 8

x = 8-5

x = 3

b) × - 4 = 3

x = 4 + 3

x = 7

c) × + 6= 5

x = 5 -6

x = -1

d) × - 7 = -7

x = -7 + 7

x = 0

e) × + 9 = - 1

x = -1 -9

x = -10

f) × - 39 = - 79

x = -79 + 39

x = -40

g) 10 = × + 8

x = 10 - 8

x = 2

h) 15 = × + 20

x = 15 - 20

x = -5

i) 4 = × - 10

x = 4 + 10

x = 14

j) 7 = × + 8

x = 7 - 8

x = -1

k) × - 1 = 5

x = 5 + 1

x = 6

l) 2 × + 4 = 16

2x = 16 - 4

x = 12/2

x = 6

m) 3× = 15

x = 15/3

x= 5

n) 2× = 10

x = 10/2

x = 5

o) 3× = - 9

x = -9/3

x = -3

p) 2× - 2 = 12 - 5 ×

2x + 5x = 12 + 2

7x = 14

x = 14/7

x = 2

q) 3× - 13 = 8

3x = 8 +13

x = 21/3

x= 7

r) 4× - 9 = 23

4x = 23 + 9

4x = 32

x = 32/4

x = 8

s) 7× - 33 = - 12

7x = -12 + 33

7x = 21

x = 21/7

x = 3

t) 33 + × = 5 - 3 ×

x + 3x = 5 - 33

4x = -28

x = -28/4

x = -7

u) 2× = 14

x = 14/2

x = 7

v) 7× = - 21

x = -21/7

x = -3

w) 4× = - 12

x = -12/4

x= -3

x) 35 × = - 105

x = -105/35

x = -3

Bons estudos!
