Question

If \[\frac{1}{3} x + 5 = 8\], then x = ?

Options

• 3

• 6

• 9

• 12

Answer 1

9

\[\frac{1}{3}x + 5 = 8\]

or, \[\frac{1}{3}x + 5 - 5 = 8 - 5\] [Subtracting 5 from both the sides]
or, \[\frac{1}{3}x = 3\]

or, \[\frac{1}{3}x \times 3 = 3 \times 3\]   [Multiplying both the sides by 3]
or, x = 9
