I need help with translating a word problem into an algebraic equation....for example:?

Question

Four is added to the quantity three minus the sum of negative seven and six. The answer is then multiplied by three. What is the result?
This is for my 13 year old's pre-algebra class. Thanks for any help!!!

Answer 1

{4 + [3- (6-7)]} 3

= {4 + [3- (-1)]} 3
= {4 + [3 +1)]} 3
= {4 + [4)]} 3
= {4+4} 3
= 8 * 3
= 24

Answer 2

the sum of -7 and 6 is simply (-7+6)

now three minus that is 3 - (-7+6)

and four added to that is 4 + 3 - (-7 +6)

the answer is then multiplied by 3 is 3(4 + 3 - (-7 +6))

Now lets start simplifying it -7+6 = -1

Subtract this from 3 to get +4 ie. 3 - (-1) = 3 + 1

Add this to 4 to get 8

Result is then multiplied by 3 8 times 3 = 24

Answer 3

ok, start at the left and anytime you get to a word like quantity or sum, you probably need a set of parentheses.

The example:

4 + (3 - (-6 +-7)

4 + (3 - (-13))

4 + 16 (subtracting a negative is the same as adding a positive)

this part of the answer is 20

20 X 3 is 60.

Answer 4

I to am 13 but the answer is 4+3-(-7+6)3 which equals 2 I THINK!

Answer 5

I remember when math was easy like this.....lol. But I also remember when it was NOT for me!

Do these kinds in pieces. Identify each piece and then when you're done put'em together.
-------------------------------------------------------------------------------
"Four is added to the quantity three minus the sum of negative seven and six."

The sum of negative 7 and 6______-7 + 6

Three minus this sum______3 - (-7 + 6)

Four is added to the QUANTITY (which means; something in parentheses) of three minus that sum______4 + [3 - (-7 + 6)]

Let's find this 'answer' before we proceed, which means to find out what it simplifies to:

==> -7 + 6 = -1

==> 3 - (-1) = 3 + 1 = 4

==> 4 + 4 = 8

So this comes out to 8......we'll need this in a sec.
---------------------------------------------------------------------------------
Next part:

"The answer is then multiplied by three."

==> 3*8

The result?___________3*8 = 24

So, the result is 24.




Make sense? Hope it helps.

Answer 6

3 x [4 + ( -7 + 6 )]

Answer 7

3*(4+(3-(-7+6)))
=24

people who are getting 60:

the sum of negative 7 and six = -7 + 6 i would have thought not -7 +(-6)

Answer 8

That's not algebra, it is arithmetic !



((3 -(-7+6)) + 4).3

Answer 9

3{4 + 3- (6-7)}

24
