01- Resolva as equações observando todas as regras que foram colocadas. a) 2x + 3 = b) 2x + 6 = 12 c) 4x + 5 = 9 d) 3x + 10 = -1 e) 5x + 4 = 2x + 5 f) 3x + 4 = 5 g) 5x + 3 = 4x + 9 h) 3x + 7 = 2x + 1 i) 6x = 12 j) 2x + 3 = 9​

Answer 1

a) 2x + 3 =

2x = 3

x = 3/2

b) 2x + 6 = 12

2x = 12-6

2x = 6

x = 6/2

x = 3

c) 4x + 5 = 9

4x = 9-5

4x = 4

x = 4/4

x = 1

d) 3x + 10 = -1

3x = -1-10

3x = -11

x = -11/3

e) 5x + 4 = 2x + 5

5x-2x = 5-4

3x = 1

x = 1/3

f) 3x + 4 = 5

3x = 5-4

3x = 1

x = 1/3

g) 5x + 3 = 4x + 9

5x-4x = 9-3

x = 6

h) 3x + 7 = 2x + 1

3x-2x = 1-7

x = -6

i) 6x = 12

x = 12/6

x = 2

j) 2x + 3 = 9

2x = 9-3

2x = 6

x = 6/2

x = 3

Bom Feriado ❤️❤️❤️
