Question

solve : 2-8x/1-5x = 3+7x/4+5x​

Answer 1

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

8-18x35x² = 3 - 8x - 35x²

8-18x38x

8-3-8x + 18x

5= 10x

5/10 = x

1/2 = x

Therefore,

x = 1/2
