Question

solve for x :
3( 7x +1 / 5x -3 ) - 4( 5x -3/ 7x +1) = 11; x is not equal to 3/5, -1/7​

Answer 1

Answer:

this is the answer above

Answer 2

Step-by-step explanation:

Let 7x + 1 / 5x - 3 = y

so the equations formed will be

3y - 4×1/y = 11

so

3y^2 -4 = 11 y

3y^2 -11 y -4 =0

by splitting

3y^2 -12y +1 y -4 = 0

3y ( y -4 ) + 1 ( y - 4 )

3y + 1 =0

3y = -1

y = -1/3

y - 4 = 0

y = 4
