Let the number be represented by ( x ). The phrase "subtract seven more than twice a number" translates to ( 2x + 7 ), and "from the square of one-third of the number" translates to ( \left(\frac{1}{3}x\right)^2 ). Therefore, you can express the equation as: [ \left(\frac{1}{3}x\right)^2 - (2x + 7) = 0. ]
