Answer 1

$\huge{\boxed{\boxed{\red{\ulcorner{\mid{\overline{\underline{\bf{Answer:-}}}}}\mid}}}}$

Verify :-

i) x = 4.

$2(4) - 3 = 9 - (4). \\ \\ 8 - 3 = 5. \\ \\ 5 = 5.$

ii) x = 2.

$6(2) + 4 = 16. \\ \\ 12 + 4 = 16. \\ \\ 16 = 16.$

iii) x = 6.

$3(6) + 2(6 + 5) = 40. \\ \\ 18 + 22 = 40. \\ \\ 40 = 40.$
