Question

3 uponx+1+ 4upon x-1= 29upon 4x-1​

Answer 1

Answer:

x=7

Step-by-step explanation:

• 3/x+1+4/x-1=29/4x-1
• 3(x-1) +4(x+1)/x*2-1=29/4x-1
• 3x-3+4x+4/x*2-1=29/4x-1
• 7x+1/x*2-1=29/4x-1

cross multiply

• 29(x*2-1) =(7x+1) (4x-1)
• 29x*2-29=28x*2-7x+4x-1
• 29x*2-29=28x*2+3x-1
• 29x*2-28x*2-3x+1-29=0
• x*2-3x-28=0
• x*2-7x+3x-28=0
• x(x-7) +3(x-7) =0
• (x+3) (x-7) =0

then x=7
