Question

calcule o valor de x ​

Answer 1

Explicação passo-a-passo:

Teorema de Tales

5x+2 / 6x+3 = 37/45

Multiplica cruzado

(5x+2)45 = (6x+3)37

225x + 90 = 222x + 111

225x - 222x = 111 - 90

3x = 21

x = 7

Answer 2

Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\mathsf{\dfrac{5x + 2}{(5x + 2) + (6x + 3)} = \dfrac{37}{37 + 45}}$

$\mathsf{\dfrac{5x + 2}{11x + 5} = \dfrac{37}{82}}$

$\mathsf{410x + 164 = 407x + 185}$

$\mathsf{410x - 407x = 185 - 164}$

$\mathsf{3x = 21}$

$\mathsf{x = \dfrac{21}{3}}$

$\boxed{\boxed{\mathsf{x = 7}}}$
