Question

4x+7/9-3x=1/4 please tell me fast
​

Answer 1

x = -1

Step-by-step explanation:

(4x+7)/(9-3x) = 1/4

=> 4x + 7 = 1/4 (9-3x)

=> 4(4x + 7) = 1(9-3x)

=> 16x + 28 = 9 - 3x

=> 16x = 9 - 3x - 28

=> 16x + 3x = 9 - 28

=> 19x = -19

=> x = -19/19

=> x = -(19/19)

x = -1

Answer 2

$\Large{\underline{\underline{\sf{Given:}}}}$

$\sf \: \: \frac{4x + 7}{9} \: = \frac{1}{4}$

Find :

=> x

Solution :

(4x+7)/(9-3x) = 1/4

=> 4x + 7 = 1/4 (9-3x)

=> 4(4x + 7) = 1(9-3x)

=> 16x + 28 = 9 - 3x

=> 16x = 9 - 3x - 28

=> 16x + 3x = 9 - 28

=> 19x = -19

=> x = -19/19

=> x = -(19/19)

x = -1
