an example would be: 9x+5m/2=24

because the variables are x and m

the numbers are 9, 5, 2, and 24

and the operation symbols are +, /, and =

Which equation has no solution?

ivann1987 [24]

Answer:

$4(x + 3) + 2x = 6(x + 2)$
$5 + 2(3 + 2x) = x + 3(x + 1)$

Step-by-step explanation:

$5(x + 3) + x = 4(x + 3) + 3 \\ 5x + 15 + x = 4x + 12 + 3 \\ 5x + x - 4x = 12 + 3 - 15 \\ 2x = 0$

Divide both sides of the equation by 2

2x/2 = 0/2

x = 0

(4+612+x)=2(3x+8)

4+612+x=6x+16

4+612-16=6x-x

600=5x

Divide both sides of the equation by 5

600/5 = 5x

120 = x

sue has 7/8 of her book left to read. If she reads another 2/7 of the book, how much of the book will she have left?

maxonik [38]

First you have to make the fractions equal.
That gives you 49/56 and 16/56.
Then you add them together and get 65/56.
So I guess she finishes the book. (not completly sure, werid)
Hope this helps
