Answer 1

Resposta:

$\textsf{Segue a resposta abaixo}$

Explicação passo-a-passo:

$\mathsf{5(x+1)+6(x+2)=9(x+3) }$

$\mathsf{5x+5+6x+12=9x+27 }$

$\mathsf{ 11x+ 17=9x+27 }$

$\mathsf{ 11x-9x=27-17}$

$\mathsf{2x=27-17 }$

$\mathsf{ 2x= 10}$

$\boxed{\boxed{\mathsf{ x=5}}}$

Answer 2

Resposta:

x = 5

$\sf{5*(×+1)+6*(×+2)=9(×+3)}$

$\sf{5x + 5 + 6(x + 2) = 9(x + 3)}$

$\sf{5x + 5 + 6x + 12 = 9(x + 3)}$

$\sf{5x + 5 + 6x + 12 = 9x + 27}$

$\sf{11x + 5 + 12 = 9x + 27}$

$\sf{11x + 17 = 9x + 27}$

$\sf{11x + 17 - 9x = 27}$

$\sf{11x - 9x = 27 - 17}$

$\sf{2x = 27 - 17}$

$\sf{2x = 10}$

$\sf{10 \div 2}$

$\rightarrow\boxed{\boxed{\sf{x = 5}}}\checkmark$
