Answer 2

RESOLVER:

$10\left(20-x\right)>8\left(2x-1\right)$

Desarrollamos:

$10\left(20-x\right)\\\\=10\cdot \:20-10x\\\\10\cdot \:20=200\\\\=200-10x$

Desarrollamos:

$8\left(2x-1\right)\\\\=8\cdot \:2x-8\cdot \:1\\\\=16x-8$

$200-10x>16x-8$

RESOLVEMOS:

$200>16x-8+10x\\\\200>26x-8\\\\200+8>26x\\\\208>26x\\\\\frac{208}{26} >x\\\\8>x\\\\\boxed{x<8}$
