Question

3(x+5)=-2(x+8)
4(x-1)=3(5x-9)
Me ajuda nesses dois​

Answer 1

Resposta:

Explicação passo-a-passo:

3(x+5)+= -2(x+8)

3x+15= -2x-16

3x+2x=-16-15

5x=-31

x- -31/5

4(x-1)=3(5x-9)

4x - 4 = 15x - 27

4x - 15x = - 27 + 4

- 11x = - 23 (-1)

11x = 23

x= 23/11

Answer 2

3(x+5)=-2(x+8)

3x + 15 = - 2x - 16

3x + 2x = - 16 - 15

5x = - 31

x= - 31/5

4(x-1)=3(5x-9)

4x - 4 = 15x - 27

4x - 15x = - 27 + 4

- 11x = - 23 (-1)

11x = 23

x= 23/11
