Question

2) Resolva as seguintes equações.
a) 2m - 3(4 - m) = 5 + 4(2m+1)
me ajudem!​

Answer 1

$\mathsf{2m-3(4-m)=5+4(2m+1)}\\\mathsf{2m-12+3m=5+8m+4}\\\mathsf{2m+3m-8m=5+4+12}\\\mathsf{-3m=21\times(-1)}$

$\mathsf{3m=-21}\\\mathsf{m=-\dfrac{21}{3}}$

$\boxed{\boxed{\boxed{\mathsf{m=-7\checkmark}}}}$
