Question

(iv) 5(x - 4) - 2(x - 9) + 5(x + 6) = 0​

Answer 1

$5(x - 4) - 2(x - 9) + 5(x + 6) = 0\\5x-20-2x+18+5x+30=0\\8x=28\\x=\dfrac{28}{8}=\dfrac{7}{2}$

Answer 2

Question-

$5(x-4) -2(x-9) + 5(x + 6) =0$

Solution-

$⟶5x - 20 - 2x + 18 + 5x + 30 = 0$

$⟶5x - 2x + 5x - 20 + 18 + 30 = 0$

$⟶8x + 28 = 0$

$⟶8x = 0 - 28$

$⟶8x = - 28$

$⟶x = \frac{ - 28}{8}$

$⟶ \frac{ - 7}{2} \: ans..$
