WebTo solve an algebraic word problem: Define a variable. Write an equation using the variable. Solve the equation. If the variable is not the answer to the word problem, use the variable to calculate the answer. For a Venn diagram: WebLet x=the number Now we can set up our equation. Seven divided by the sum of a number and two 7x+2 is equal to 7x+2= half the difference of the number and three. 7x+2=x−32 Before we solve, take note that there's a variable in the denominator which means we will have a restricted value. So, x≠−2 because that would make the denominator zero ...
