Answer:Hi ,
It is given that ,
( 2 - 7x )/( 1 - 5x ) = ( 3 + 7x )/( 4 + 5x )
Do the cross multiplication ,
( 2 - 7x )( 4 + 5x ) = ( 3 + 7x )( 1 - 5x )
2(4 + 5x)-7x(4+ 5x)=3(1-5x)+7x( 1 - 5x)
8+10x - 28x - 35x² = 3 - 15x+7x - 35x²
8 - 18x - 35x² = 3 - 8x - 35x²
8 - 18x = 3 - 8x
8 - 3 = - 8x + 18x
5 = 10x
5/10 = x
1/2 = x
Therefore ,
x = 1/2
I hope this helps you.
