Question

solução dessa conta ?7(2x-7)=5(2x+5)

Answer 1

$7(2x-7)=5(2x+5)\to \\\\ 14x-49=10x+25\to \\\\ 14x-10x=25+49\to \\\\ 4x=74\to \\\\ x= \dfrac{74}{4}\to \\\\\\ \boxed{x= \frac{37}{2} ~~ou~~x=18,5 }$

Answer 2

$7(2x-7)=5(2x+5) \\ \\ 7*2x - 7*7 = 5*2x +5*5 \\ 14x - 49 = 10x +25 \\ 14x - 10x = 25 + 49 \\ 4x = 74 \\ x = \frac{74}{4} = \frac{37}{2} \\ x = 18,5$
