Question

solve for x 4x+1 upon 5x -1 = 8x -1 upon 10x + 1 give step by step explanation​

Answer 1

Answer:

x = 0

Step-by-step explanation:

4x + 1/ 5x - 1 = 8x -1 / 10x + 1

Cross multiply the eq.

( 4x + 1 )( 10x + 1 ) = ( 8x - 1 )( 5x - 1 )

40x^2 + 4x + 10x + 1 = 40x^2 - 8x - 5x + 1

40x^2 and 1 gets canceled

14x = -13x

14x + 13x = 0

27x = 0

so

x = 0

I hope it is helpful for you...

Answer 2

Answer:

x = 2/19

Step-by-step explanation:

4x+1/5x-1 = 8x-1/10x+1

By cross - multiplication

(10x-1)(4x+1) = (5x-1)(8x-1)

After Multiplying

40x^2 + 10x - 4x - 1 = 40x^2 - 5x - 8x + 1

After Rearranging

40x^2 - 40x^2 + 10x + 8x = -5x + 4x + 1 + 1

0 + 18x = -1x + 2

18x = -x + 2

Rearranging

18x + x = 2

19x = 2

x = 2/19
