Question

c)4x + 2 = 18
d) 12 = 6x +36
e) 2 a - 6 = 18
f) 3x + 6 = 2x + 20​

Answer 1

Resposta:

c) x=4

d) x= 8

e) a = 12

f) x=14

Explicação passo-a-passo:

c) 4x+2=18

4x=18-2

4x= 16

x=16/4

x=4

d) 12 = 6x +36

6x= 36+12

6x= 48

x= 48/6

x= 8

e) 2a - 6 = 18

2a = 18 + 6

2a = 24

a = 24/2

a = 12

f) 3x+6=2x+20

3x-2x=20-6

1x=14

x=14/1

x=14
