Question

resolva as equações a seguir :)​

Answer 1

Resposta:

a) 3 + x = 0

x = -3

b) 2x - 2 = 2

2x = 2 + 2

2x = 4

x = 4/2

x = 2

c) 4x - 7 = 25

4x = 25 + 7

4x = 32

x = 32 /4

x = 8

d) 5x - 5 = 30

5x = 30 + 5

5x = 35

x = 35/5

x = 7

e) 4x + 5 = 45

4x = 45 - 5

4x = 40

x = 40/4

x = 10

bons estudos!
