12-2x=-2(y-x) error analysis

Sagot :

Answer:

=> 12 - 2x = -2y + 2x

  • subtract 12 from both sides

=> 12 - 12 - 2x = -2y + 2x - 12

  • simplify

=> -2x = -2y + 2x - 12

  • subtract 2x from both sides

=> -2x - 2x = -2y + 2x - 2x - 12

  • Simplify

=> -4x = -2y - 12

  • divide both sides by -4

=> -4x/-4 = -2y/-4 - 12/-4

  • Simplify

=> x = 1/2y + 3...ans
