A number :

$x$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

3/5 of it :

$\frac{3}{5} x$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

2/7 of it :

$\frac{2}{7} x$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

3/5 of a number exceeds its 2/7 by 44 thus :

$\frac{3}{5} x - \frac{2}{7} x = 44$

(( Find the number )) ---¢ x asked

So we need to solve the above equation for x.

$\frac{3}{5} x - \frac{2}{7} x = 44$

Multiply sides by 35

$(35) \times ( \frac{3}{5} x) - (35) \times ( \frac{2}{7} x) = 35 \times 44$

$(7 \times 3x) - (5 \times 2x) = 4 \times 35 \times 11$

$21x - 10x = 140 \times 11$

$11x = 11 \times 140$

Divide sides by 11

$\frac{11}{11} x = \frac{11 \times 140}{11}$

$x = 140$

Done...
