Answer 1

Answer:

when we reciprocal the value -x go to +x then we add 2x+x = 3x and then 7-5 =2

Answer 2

Answer:

$x = \frac{51}{15}$

Step-by-step explanation:

here, $\frac{3 (2x - 5)}{7 - x} = \frac{3}{2}$

      ⇒ $\frac{6x - 15}{7-x} = \frac{3}{2}$        [by cross multiplication]

      ⇒ $2 (6x - 15) = 3 (7-x)$

      ⇒ $12x - 30 = 21 - 3x$

      ⇒ $12x + 3x = 21 + 30$

      ⇒ $15x = 51$

      ⇒ $x = \frac{51}{15}$
