  1. Solve for x: 2x + 5 = 15

    Answer: 5

    To solve for x, subtract 5 from both sides of the equation: 2x + 5 - 5 = 15 - 5, so 2x = 10. Now, divide both sides by 2: 2x ÷ 2 = 10 ÷ 2, so x = 5.

  2. What is the value of x in the equation 4x - 3 = 9?

    Answer: 3

    Add 3 to both sides of the equation: 4x - 3 + 3 = 9 + 3, so 4x = 12. Now, divide both sides by 4: 4x ÷ 4 = 12 ÷ 4, so x = 3.

  3. Simplify the expression: 3x + 4x - 5

    Answer: 7x - 5

    Combine like terms: 3x + 4x = 7x, so the simplified expression is 7x - 5.

  4. Solve for y: 2y - 7 = 3y + 4

    Answer: -4

    First, subtract 2y from both sides: 2y - 7 - 2y = 3y + 4 - 2y, so -7 = y + 4. Next, subtract 4 from both sides: -7 - 4 = y + 4 - 4, so y = -11.

  5. Which of the following is a solution to the equation x² - 4 = 0?

    Answer: x = ±2

    To solve x² - 4 = 0, add 4 to both sides: x² = 4. Now, take the square root of both sides: x = ±√4, so x = ±2.
