Question

7(2x-3)+2(x+1)-5(x -9)=3x+10 o valor do x obrigada.​

Answer 1

Resposta:

Explicação passo-a-passo:

7(2x-3)+2(x+1)-5(x -9)=3x+10

14x - 21 + 2x + 2 - 5x + 45 = 3x + 10

14x + 2x - 5x - 3x = 10 - 45 - 2 + 21

8x = -16

x = -16/8

x = -2

Answer 2

$7(2x - 3) + 2(x + 1) - 5(x - 9) = 3x + 10$

14x-21+2x+2-5x+45=3x+10

14x+2x-5x-3x=21-2-45+10

16x-8x=-16

8x=-16

x=-16\8

x=-2
