Question

5x - 3 (x - 2) maior 20 - 2x

Answer 1

5 x - 3 ( x - 2 ) > 20 - 2 x
5 x - 3 x + 6 > 20 - 2 x
5 x - 3 x + 2 x > 20 - 6
4 x > 14
x = 14 / 4
x = 3,5

Answer 2

$5x-3(x-2)\ \textgreater \ 20-2x\\5x-3x+6\ \textgreater \ 20-2x\\5x-3x+2x\ \textgreater \ 20-6\\4x\ \textgreater \ 14\\x\ \textgreater \ \frac{14}{4}~~~~~~x\ \textgreater \ 3,5$
