Solution

Let's translate each of the given statements into equations:

  1. Statement: Adding four to the number and then multiplying by three gives the same result as multiplying the number by three and then adding twelve.
    Equation: (x+4)×3=3x+12(x + 4) \times 3 = 3x + 12

  2. Statement: Tripling it and then subtracting five is the same as subtracting five from it and then tripling the result.
    Equation: 3x5=3(x5)3x - 5 = 3(x - 5)

  3. Statement: Multiplying it by seven and then adding ten results in the same value as adding ten to it and then multiplying by seven.
    Equation: 7x+10=7(x+10)7x + 10 = 7(x + 10)

  4. Statement: Halving it and then adding eight is the same as adding eight to it and then halving the result.
    Equation: x2+8=x+82\frac{x}{2} + 8 = \frac{x + 8}{2}

  5. Statement: Subtracting six from the number and then multiplying by four gives the same result as multiplying the number by four and then subtracting twenty-four.
    Equation: (x6)×4=4x24(x - 6) \times 4 = 4x - 24

  6. Statement: Adding seven to the number and then doubling it is the same as doubling the original number and adding fourteen.
    Equation: (x+7)×2=2x+14(x + 7) \times 2 = 2x + 14

  7. Statement: Subtracting ten from a number and then multiplying by five yields the same result as multiplying the number by five and then subtracting fifty.
    Equation: (x10)×5=5x50(x - 10) \times 5 = 5x - 50

  8. Statement: Multiplying it by eight and then adding twelve is the same as adding twelve to it and then multiplying by eight.
    Equation: 8x+12=8(x+12)8x + 12 = 8(x + 12)

  9. Statement: Dividing it by four and then adding three is the same as adding three to it and then dividing by four.
    Equation: x4+3=x+34\frac{x}{4} + 3 = \frac{x + 3}{4}

  10. Statement: Tripling it and then subtracting twelve results in the same value as subtracting it by twelve and then tripling the result.
    Equation: 3x12=3(x12)3x - 12 = 3(x - 12)


Would you like a detailed explanation of any of these equations, or do you have any questions?

Here are 8 related questions for further practice:

  1. Translate the statement "Doubling the number and adding five is equal to adding five to the number and doubling it" into an equation.
  2. Solve the equation (x+4)×3=3x+12(x + 4) \times 3 = 3x + 12.
  3. What happens if you simplify the equation 3x5=3(x5)3x - 5 = 3(x - 5)?
  4. Translate and solve: "Multiplying a number by 5 and subtracting 15 is the same as subtracting 15 and then multiplying by 5."
  5. Solve the equation x2+8=x+82\frac{x}{2} + 8 = \frac{x + 8}{2}.
  6. Explain why (x10)×5=5x50(x - 10) \times 5 = 5x - 50 holds true for all x.
  7. Simplify the equation 8x+12=8(x+12)8x + 12 = 8(x + 12).
  8. If you divide a number by 4 and add 3, what operation would yield the same result if you reverse the order?

Tip: When translating word problems into equations, look for key phrases like "adding," "subtracting," "multiplying," or "dividing," and pay attention to the order in which operations are performed.
