Example Question #3 : Solving Linear Equations In Word Problems. Write as an equation: Five-sevenths of the difference of a number and nine is equal to forty. Possible Answers: Correct answer: Explanation: "The difference of a number and nine" is the result of a subtraction of the two, so we write this as. "Five-sevenths of" this difference is ... When the transfer began, the drive had blank megabytes of files on it. So, when the transfer began, that would be t equals zero. T equals zero was right when the transfer began. So t equals zero. S of zero is going to be five times zero, five times zero plus 45, which of course is just going to be equal to 45. Linear Equation Word Problem. Problem stated in words are known as word problems.
