MCQ

Find $x; \ (i)\ x -4 = 3\ (ii) \ 9x = 81\ (iii)\ x + 6 = 10$

✓
$x = 7, 9, 4$
B
$x = -1, 7, -7$
C
$x = -1, 4, 5$
D
$x = -3, 6, 7$

✓

Answer

Correct option: A.

$x = 7, 9, 4$

$(i). x - 4 = 3$
$x = 3 + 4$
$x = 7$
$(ii). 9x = 81$
$x = 9$
$\text{x}=\frac{81}{9}$
$(iii). x + 6 = 10$
$x = 10 - 6$
$x = 4$
$x = 7, 9, 4$
