  x = -1

  Step-by-step explanation:

  10x + 3 = 3x - 4

  10x + 3 - 3 - 3x = 3x - 3x - 4 - 3

  10x - 3x = -4 - 3

  7x = -7

  

  x = -1

  check x = -1

  10x + 3 = 3x - 4

  10(-1) + 3 = 3(-1) - 4

  -10 + 3 = -3 - 4

  -7 = -7

  x=-1

  Step-by-step explanation:

  10x-3x+3=-4 move variable to the left hand side and change its sign

  10x-3x=-4 -3 collect like terms

  7x= -7 divide boty side of the equation by 7

  final answer. x=-1
