18

Step-by-step solution

5 steps
  1. የመነሻውን ቁጥር xx ብለን እንውሰድ። የተሰጡትን ደረጃዎች በመጠቀም እኩልታውን እንፍጠር።

    • ቁጥሩ በ −4-4 ተባዝቷል: −4x-4x
    • በ 18 ቀንሷል: −4x−18-4x - 18
    • በ 2 ተካፍሏል: −4x−182\frac{-4x - 18}{2}
    • ከዚያም በ 35 ጨምሯል: −4x−182+35\frac{-4x - 18}{2} + 35
    • የመጨረሻው መልስ −10-10 ነው:
    −4x−182+35=−10\frac{-4x - 18}{2} + 35 = -10
  2. xx ያለበትን ክፍል ለመለየት ከሁለቱም የእኩልታው ጎኖች 35 ን እንቀንስ።

    −4x−182=−10−35\frac{-4x - 18}{2} = -10 - 35 −4x−182=−45\frac{-4x - 18}{2} = -45
  3. ከሁለቱም የእኩልታው ጎኖች በ 2 እናባዛ።

    −4x−18=−45×2-4x - 18 = -45 \times 2 −4x−18=−90-4x - 18 = -90
  4. ከሁለቱም የእኩልታው ጎኖች 18 ን እንጨምር።

    −4x=−90+18-4x = -90 + 18 −4x=−72-4x = -72
  5. xx ን ለማግኘት ከሁለቱም የእኩልታው ጎኖች በ −4-4 እናካፍል።

    x=−72−4x = \frac{-72}{-4} x=18x = 18

    የመነሻው ቁጥር 18 ነው።

    18
