  1. Solve for x: 3x + 7 = 22

    Answer: x = 5

    Subtract 7 from both sides to get 3x = 15, then divide by 3 to get x = 5.

  2. Solve for x: 2x - 4 = 10

    Answer: x = 7

    Add 4 to both sides to get 2x = 14, then divide by 2 to get x = 7.

  3. What is the slope of the line y = 4x - 3?

    Answer: 4

    In slope-intercept form y = mx + b, the coefficient m = 4 is the slope.

  4. What is the y-intercept of the line y = -2x + 6?

    Answer: 6

    The y-intercept is the constant term b = 6 in y = mx + b form.

  5. Solve for x: 5(x - 2) = 15

    Answer: x = 5

    Divide both sides by 5 to get x - 2 = 3, then add 2 to get x = 5.

  6. If 4x + 8 = 0, what is x?

    Answer: x = -2

    Subtract 8 from both sides to get 4x = -8, then divide by 4 to get x = -2.
