 Question 486101: How can I rewrite the expression using parentheses to get the given value of 28-3x3+4 with the value being 23? Answer by bucky(2189)   (Show Source): You can put this solution on YOUR website!I notice that your mathematical expression uses "x" as meaning multiplication. . You can set this up as an equation. When you do it looks like this: . 28 - 3 x 3 + 4 = 23 . You can make this an equality (both sides are equal) by inserting one set of parentheses as follows: . 28 - (3 x 3) + 4 = 23 . Inside of the parentheses the 3 x 3 equals 9. Substituting 9 for the contents inside the parentheses changes the left side to: . 28 - 9 + 4 = 23 . If you algebraically total the three numbers on the left side by subtracting 9 from 28 and then adding 4 to that answer, the equation becomes: . 23 = 23 . So the answer to your problem is to insert parentheses as shown below and the result will equal 23: . 28 - (3 x 3) + 4 . Hope this helps you understand the problem better.
