Question

equação 1 grau 3(x+3)-1=2​

Answer 1

$3(x + 3) - 1 = 2 \\ \\ 3(x + 3) = 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (\div 3)\\ \\ x + 3 = 1 \\ \\ x = -2$

Answer 2

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

$\mathsf{x=-\dfrac{6}{3}}$

$\large\boxed{\boxed{\mathsf{x=-2}}}$
