Question

1,9 x - 3,6 = x 10,8 ?​

Answer 1

Resposta:

$x=-\frac{36}{89}$

Explicação passo a passo:

$1.9x-3.6=x\cdot \:10.8$

$1.9x\cdot \:10-3.6\cdot \:10=x\cdot \:10.8\cdot \:10$

$19x-36=108x$

$19x-36+36=108x+36$

$19x=108x+36$

$19x-108x=108x+36-108x$

$-89x=36$

$\frac{-89x}{-89}=\frac{36}{-89}$

$x=-\frac{36}{89}$
