Question

resolver esta ecuación 3/4 (x-4) =(x+4)

Answer 1

3/4(x-4)= (x+4)
3/4x - 3 = x + 4
3/4x - 3 - 4 - x = 0
3/4x - 7 - x = 0
3/4x - x = 7
-1/4x = 7
(- 4)( -1/4x) = 7(-4) --->multiplica por el recíproco
X= -28

Answer 2

$\frac{3}{4} x (x-4)= x+4$
$\frac{3}{4}x -3= x+4$
$4 x \frac{3}{4}x - 4x3 = 4x+4x4$
$3x-12=4x+16$
3x-4x=16+12
-x=28
x=-28
