~ Simplifying

4x + -3 = 2(2x + -1)

~ Reorder the terms:

-3 + 4x = 2(2x + -1)

~ Reorder the terms:

-3 + 4x = 2(-1 + 2x)

-3 + 4x = (-1 * 2 + 2x * 2)

-3 + 4x = (-2 + 4x)

~ Add '-4x' to each side of the equation.

-3 + 4x + -4x = -2 + 4x + -4x

~ Combine like terms: 4x + -4x = 0

-3 + 0 = -2 + 4x + -4x

-3 = -2 + 4x + -4x

~ Combine like terms: 4x + -4x = 0

-3 = -2 + 0

-3 = -2

~ Solving

-3 = -2

~ This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Suppose David had $65 to spend on his ticket and some shirts. He already used $32.25 on his ticket and the shirts are $14.50. Ho
DiKsa [7]
We know $65 were spent on his ticket and some shirts.Which he used 32.25 which leaves us  with 27.75 and a shirt cost 14 and 50 cent .

SO you need to divide 27.75 in 14 and 50 cents which is equal to
   
             14 plus 14 equals 28
              75 plus 50 equals 1 and 25 cents

David can buy two shirts 

Hope this helped

Where can u place these at tell me
Alex777 [14]
The best thing to do is to rewrite the fractions as decimals
-2/3 is approx. equal to -0.6666667
So a little past half way (to the left) between -1 and 0
1 1/5 is 1.5 so that is right between 1 and 2

Hope this helps :)
