Question

resolva as equações:

a) x+8+3x= 24

b) 3x+8-x=10

c) 3k- 2= 25

d)3a- 12 +a =12​

Answer 1

Explicação passo-a-passo:

a) x+8+3x = 24

4x = 24-8

4x = 16

x =4

b) 3x+8-x = 10

2x = 10 -8

2x = 2

x = 2/2 =1

c) 3k-2 = 25

3k = 25+2

3k = 27

k = 9

d) 3a-12+a=12

4a = 12+12

4a = 24

a = 24/4 = 6
