Okay, Maths! Let's get you ready for your exam. Here's a typical algebra question focusing on solving linear equations.

Question: Solve for x: 3x + 7 = 19

Answer:

  1. Write down the equation.

    3x + 7 = 19

  2. Isolate the term with x by subtracting 7 from both sides of the equation.

    3x + 7 - 7 = 19 - 7
    3x = 12

  3. Solve for x by dividing both sides by 3.

    (3x)/(3) = 12/3
    x = 4

    The solution is x = 4.
