using only addition, subtraction, multip, and divison

(15 * 2 - 6 - 3)/3 = 7
by Level 3 User (2.1k points)
yeah..that was a good solution
It uses 3 twice.  ("I like 3")

If you can use a number more than once, then the answer is trivial:

2/2 + 3/3 + 6/6 + 15/15 + 15/15 + 15/15 + 15/15 = 7, etc.
slope 7/6 and y-intercept (0,1/3)

This is a shame most of us looking at this should be out of school and college and the sad part about it is most of you that are out of college have answered this problem incorrectly.

Read the problem write it out if you must but you should be able to do it in your brain very simply.

I have seen the correxct answer on 3 or 4 times.

write it this way same way your going to do it in your mind:

(15 times 2 = 30-6=24-3=21 divided by 3= (7)

(15 * 2 - 6 - 3 ) /3 = 7

GOT IT NOW

How do you divide a whole number by an algebraic term.

• 25x - 10                   5-2
•     5x                =        x

My book do not give any example by display nor the rules in previous pages or chapters to help solve (simplify) this problem though the book do give the answer.

Why do the " x " remain in the answer?

by
This is the Solution

(6x2) - (15/3) = 7    ??? amhhmmm

I am trying to help my daughter with her homework.  They are asking for an example of an addition problem that can be solved using the distributive property and requiring 2 addends and 4 digits.

I'm thinking an answer could be 2(2222 + 1111) = 4444 + 2222 = 6666.

Does this seem correct?

I don't think that the solution using 3 twice is valid. You are required to use only the four given numbers.

The correct answer was given on Sept. 21, 2012.

(15/2) - (3/6) = 7

7.5 - 0.5 = 7
