Will mark u as the brainliest ​

Answer 1

Answer:

$\frac{5x}{3} - 4 = \frac{2x}{5} \\ \frac{5x}{3} - \frac{2x}{5} = 4 \\ taking \: lcm \: of \: 3 \: and \: 5 \\ 15 \: is \: the \: lcm \\ \frac{25x - 6x}{15} = 4 \\</p><p></p><p> \\ \frac{19x}{15} = 4 \\ 19x = 4 \times 15 = 60 \\ x = \frac{60}{19}$

Answer 2

Answer:

5x/3-4 = 2x/5

By cross multiplication

=> 5(5x-4) = (2x) (3)

=> 25x-20 = 6x

=> 25x-6x = 20

=> 19x = 20

Divide 19 both side

=> x = 20/19
