Solution

The correct option is D
-2

Given: 7(x - 1) = 3 (x - 5)

$\Rightarrow$ 7x - 7 = 3x -15 [Removing brackets]

Moving all x terms to LHS and constants to RHS, we get

7x - 3x = -15 + 7

4x = -8

Divide both sides by 4

x = -2

3 x^{- 2} + 7 x^{- 1} + 5 = 0

Solve for x and y:

$3 x - 5 y - 19 = 0, - 7 x + 3 y + 1 = 0.$

\sqrt{3 x^{2} - 7 x - 30} + \sqrt{2 x^{2} - 7 x - 5} = x + 5

(x + 5) - 7 (x - 2) \geq 4 x + 9, 2 (x - 3) - 7 (x + 5) \leq 3 x - 9
