Answer 1

Answer:

2-7x/1-5x = 3+7x/4+5x

by cross multiplication,

(2-7x)(4+5x)=(1-5x)(3+7x)

2(4+5x) -7x(4+5x)=1(3+7x)-5x(3+7x)

8+10x-28x-35x=3+7x-15x-35x

By Transposing the terms

10x-28x-35x+35x+15x-7x=3-8

-10x=-5

x=-5/-10

x=1/2

Check;x=1/2

2-7(1/2)/1-5(1/2) = 3+7(1/2)/4+5(1/2)

L.H.S. R.HS.

4-7/2 ÷ 2-5/2 6+7/2 ÷ 8+5/2

-3/2×2/-3 13/2×2/13

1 = 1

L.H.S. = R.H.S.

Hence Verified
