Question

Resolva as equações.​

Answer 1

Resposta:

a) 2x = -8

x = -8/2

x = - 4

b) 3y = 18

y = 18/3

y = 6

c) 2x = 0

x = 0/2

x = 0

d) 2x + 4 = 6

2x = 6 - 4

2x = 2

x = 2/2

x = 1

e) - 3x = 6

x = 6/-3

x = - 2

f) 4x = - 16

x = -16/4

x = -4

g) -2y = 0

y = 0/-2

y = 0

h) 3y + 1 = 10

3y = 10 - 1

3y = 9

y = 9/3

y = 3
