Question

1) Resolva as equações:


a) a + 5 = -7

b) x - 2 = -10

c) a + 5 = -7

d) y – c = +8

e) 2.x = -8

f) p/3 = -4


Por favor

Answer 1

a) a + 5 = -7

a = -7 - 5

a = -12

b) x - 2 = -10

x = -10 + 2

x = -8

c) a + 5 = -7

a = -7 - 5

a = -12

d) y – c = +8

y = 8+c

e) 2.x = -8

x = -8/2

x = -4

f) p/3 = -4

p = -4x3

p = -12

Answer 2

Boa Noite :)

A)

a + 5 = - 7

a = - 7 - 5

a = - 12

B)

x - 2 = - 10

x = - 10 + 2

x = - 8

C)

a + 5 = - 7

a = - 7 - 5

a = - 12

D)

y - c = + 8

y = 8 + c

E)

2.x = - 8

x = - 8 / 2

x = - 4

F)

p / 3 = - 4

p = - 4 × 3

p = - 12
