Answer 1

Answer:

x = 1

explanation:

$\sf \rightarrow \dfrac{3}{x} -1 = 2$

$\sf \rightarrow \dfrac{3}{x} = 2+1$

$\sf \rightarrow \dfrac{3}{x} = 3$

$\sf \rightarrow {3} = 3(x)$

$\sf \rightarrow \dfrac{3}{3} = (x)$

$\sf \rightarrow x = 1$

checking if x = 1,

$\sf \rightarrow \dfrac{3}{1} -1 = 2$

$\sf \rightarrow3 -1 = 2$

$\sf \rightarrow 2 = 2$

→ Hence proved x : 1 as L.H.S = R.H.S

Answer 2

Step-by-step explanation:

$\frac{3}{x} - 1 = 2$

Adding 1 on both sides, we get

$\frac{3}{x} - 1 + 1 = 2 + 1 \\ \frac{3}{x} = 3$

By performing cross multiplication, we get

$3 \times x = 3 \times 1 \\ 3x = 3$

Dividing both sides by 3, we get

$\frac{3x}{3} = \frac{3}{3} \\ x = 1$

Hence, the value of x is 1.
