Explicação passo a passo:
[tex]\mathsf{\dfrac{5x + 2}{(5x + 2) + (6x + 3)} = \dfrac{37}{37 + 45}}[/tex]
[tex]\mathsf{\dfrac{5x + 2}{11x + 5} = \dfrac{37}{82}}[/tex]
[tex]\mathsf{410x + 164 = 407x + 185}[/tex]
[tex]\mathsf{410x - 407x = 185 - 164}[/tex]
[tex]\mathsf{3x = 21}[/tex]
[tex]\mathsf{x = \dfrac{21}{3}}[/tex]
[tex]\boxed{\boxed{\mathsf{x = 7}}}[/tex]
