g) 6x + 10 = x + 20
h) 3x + 3 = 2x + 10
Resolva as equações de 1° grau acima presiso disso pra entregar hj me ajudem pfvr ​

Answer 1

Resposta:

a) 2x = 2 +3 + x

2x - x = 2 + 3

x=5

b) x + x = 16 - 2

2x = 14

x= 14/2

x=7

c) 3x = -x +16

3x +x = 16

4x = 16

x= 16/4

x=8

d) 2x +2 = 12

2x = 12 -2

2x= 10

x= 10/2

x=5

e) 2x +10 = 20

2x = 20 - 10

2x= 10

x= 10/2

x=5

f) 8x = 24 +5x

8x -5x = 24

3x = 24

x= 24/3

x=8

g) 6x +10 = x +20

6x -x = 20 -10

5x = 10

x= 10/5

x=2

h) 3x +3 = 2x +10

3x -2x = 10 -3

x=7
