Question

Resolver o valor do X

Answer 1

Resposta:

a) 25

b) 30

c) 19,076

Explicação passo-a-passo:

3x - 14 + 5x - 6 = 180

8x - 20 = 180

8x = 180 + 20

8x = 200

x = 200/8

x= 25

2x - 12 + 4x + 12 = 180

6x = 180

x = 180/6

x = 30

3x + 2 + 10x - 70 = 180

13x - 68 = 180

13x = 180 + 68

13x = 248

x = 248/13

x = 19,076

Answer 2

Resposta:

a) 25

b) 30

c) 19,07

Explicação passo-a-passo:

a) 3x-14+5x-6=180

8x-20=180

8x=180+20

8x=200

x=200/8

x=25

b) 2x-12+4x+12=180

6x=180

x=180/6

x=30

c) 3x+2+10x-70=180

13x-68=180

13x=180+68

13x=248

x=248/13

x=19,07
