Question

1.2x+18/25=5x-39/25 find tge value of x​

Answer 1

$1.2x + \frac{18}{25} = 5x - \frac{39}{25} \\ \\ \therefore \: \frac{18}{25} + \frac{39}{25} = 5x - 1.2x \\ \\ \therefore \: \frac{18 + 39}{25} = 3.8x \\ \\ \therefore \frac{57}{25} = 3.8x \\ \\ \therefore3.8x = \frac{57}{25} \\ \\ \therefore \frac{38x}{10} = \frac{57}{25} \\ \\ \therefore \: x = \frac{57}{25} \times \frac{10}{38} \\ \\ \therefore \: x = \frac{5 \times 2}{5 \times 5} \times \frac{19 \times 3}{19 \times 2} \\ \\ \therefore \: x = \frac{2}{5} \times \frac{3}{2} \\ \\ \therefore \: x = \: \frac{3}{5}$
