Question

Solve the equation: 3x - 7 = 20

Answer

Here’s how to solve the equation 3x - 7 = 20 step-by-step:
1. Isolate the x term:
  • Add 7 to both sides of the equation:
    3x - 7 + 7 = 20 + 7
  • This simplifies to:
    3x = 27
2. Solve for x:
  • Divide both sides of the equation by 3:
    (3x) / 3 = 27 / 3
  • This gives you:
    x = 9
Therefore, the solution to the equation 3x - 7 = 20 is x = 9.
