Answer 2

Step-by-step explanation:

Hey mate!

$\tt \dfrac{5-7x}{2(1+2x)}= - \dfrac{8}{7}$

$\tt \implies \dfrac{5-7x}{2+4x}= - \dfrac{8}{7}$

$\tt \implies -8(2+4x)=7(5-7x)$

$\tt \implies -16-32x=35-49x$

$\tt \implies 49x-32x=35+16$

$\tt \implies 17x= 51$

$\tt \implies x= \dfrac{51}{17}$

$\tt \implies x=3$

Hope it helps you mate!
