Question

A) x + 11 + 8x = - 4 + 5x -1 B) - 2x + 13 - 4x = -2 + 3x + 3 C) 3 (X + 2) +2 (X + 5) = 9


D) 2x - 1 x - 1
_____ = x - ______
3 5

E) 2(x - 1 ) 3x - 6
_____ = _____
3 5

F) 3 ( x - 5) 2x
____ = ____ = 7
6 4

Answer 1

a)x + 11 + 8x = - 4 + 5x -1
  9x +11= - 5 + 5x
  9x - 5x= - 5 - 11
  4x = -16
  X= - 4

b)- 2x + 13 - 4x = -2 + 3x + 3
   -6x +13 =1+3x
   -6x - 3x =1 -13
   -9x = -12
   x= 4/3

c)3 (X + 2) +2 (X + 5) = 9
   3x+6+2x+10=9
   5x+16=9
   5x=9 -16
   5x= -7
   x= -7/5

d)2x -1x -1
  2x  -x -1
  x -1

e)2(x - 1 ) 3x - 6
  2x3 (( x -1)x-1)
  6(x² -x -1)

f)3 ( x - 5) 2x
  6x.(x-5)
  6x² -30x
