Question

x/+4x=15-(-x-6)
2(2x-4)=(x/2+4)
me ajudem

Answer 1

X/+4x=15-(-x-6)

  x = 15 + x + 6  ==> 1 = 21 + x
4x                              4

4(21+x) = 1 ==> 84 + 4x = 1

4x = 1 - 84 ==> 4x = - 83 ==> x = - 83/4
===============================================
2(2x-4)=(x/2+4)

4x - 8 = x + 4
             2

2( 4x - 8 ) = x + 8 ==> 8x - 16 = x + 8

8x - x = + 8 + 16

7x = 24

x = 24/7
