Question

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

Answer 1

(2x+1)/(7x-2)=3/5
=> 5(2x+1) = 3(7x-2)
=> 10x+5=21x-6
=> 10x+21x=-6-5
=>11x=11
=> x=1

Answer 2

Hey mate, here is your answer -:)

____________________________

$\: \: \: \: \: \: \: \frac{2x + 1}{7x - 2} = \frac{3}{5} \\ \\ \: \: 5(2x + 1) = 3(7x - 2) \\ \: \: \: \: \: 10x + 5 = 21x - 6 \\ 10x - 21x = - 6 - 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: - 11x = - 11 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{ - 11}{ - 11} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = 1$
