Question

find the answer 4(x+2)/5 =7+5x/3

Answer 1

$4(x + 2)l5 = 7 + 5xl3 \\ (4x + 8)l5 = (21 + 5x)l3 \\ 12x + 24 = 105 + 25x \\ 12x - 25x = 105 - 24 \\ - 13x = 81 \\ x = 81l - 13 \\ x = - 6.38$

Answer 2

The correct answer is "x = -11/13".

Step-by-step explanation:

$The \ given \ expression \ is:\\\\\frac{4(x+2)}{5}=\frac{7+5x}{3}\\\\ \frac{4x+8}{5} =\frac{7+5x}{3}\\\\ On \ applying \ cross \ multiplication,we \ get\\\\3(4x+8)=5(7+5x)\\\\12x+24=35+25x\\\\On \ subtracting \ "25x" \ from \ both \ sides,we \ get\\\\12x+24-25x=35+25x-25x\\\\-13x+24=35\\\\On \ subtracting \ "24" \ from \ bth \ sides,we \ get\\\\-13x+24-24=35-24\\\\-13x=11\\\\x=-\frac{11}{13}$
