Question

D— 5.(x+1)-3.(x+2)=0
E— 13+4.(2x-1)=5.(x+2)

Answer 1

D)

5(x + 1) - 3(x + 2)= 0

5x + 5 - 3x - 6= 0

5x - 3x= 0 - 5 + 6

2x= 1

x= 1/2

E)

13 + 4(2x - 1)= 5(x + 2)

13 + 8x - 4= 5x + 10

8x - 5x= 10 - 13 + 4

3x= 1

x= 1/3

Answer 2

Resposta:

D- x=1/2

E= x=1/3

Explicação passo-a-passo:

5.(x+1) - 3.(x+2)= 0

5x+5 - 3x-6 =0

5x -3x = 0 -5 + 6

2x = 1

x= 1/2

13+ 4.(2x-1) = 5.(x+2)

13+ 8x-4 = 5x+ 10

8x - 5x = 10 -13 +4

3x = 1

x=1/3
