x=−3x=-3

Here the steps

2x+1−1x−1=2xx2−12x+1-1x-1=2xx2-1

x−3(x+1)(x−1)=2x(x+1)(x−1)x-3x+1x-1=2xx+1x-1

(x+1)(x−1)x+1x-1

x−3=2xx-3=2x

x=−3x=-3

So the answer comes out to be x = 3 I hope this was helpful

When printing an article of 2400 words, an entrepreneur decides to use two sizes of letters, using the largest one a printed pag

olga55 [171]

Step-by-step explanation:

x= Number of small pages

y= Number of full pages

1 x + 1 y = 21 .............1

Total words

1200 x + 1500 y = 27000 .............2

Eliminate y

multiply (1)by -1500

Multiply (2) by 1

-1500 x -1500 y = -31500

1200 x + 1500 y = 27000

Add the two equations

-300 x = -4500

/ -300

x = 15

plug value of x in (1)

1 x + 1 y = 21

15 + y = 21

y = 21 -15

y = 6

x= 15 Number of small pages

y= 6 Number of full pages
