Answer 1

Answer:

x=4

Step-by-step explanation:

Half a number increased by 10 is 12

Let the unknown number be x

$x \div 2 + 10 = 12$

$\frac{x}{2} + 10 = 12 \\ \frac{x + 20}{2} = 12 \\ x + 20 = 24 \\ x = 24 - 20 = 4$

Verification:

4/2 + 10 = 2+10 = 12

Answer 2

Solution -

Firstly,

• Let the required number be x.

Now, it is given that half of the number increased by 10 is 12.

⠀

According to the question

$\tt:\implies\: \: \: \: \: \: \: \: {\dfrac{1}{2}x + 10 = 12}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {\dfrac{1}{2}x = 12 - 10}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {\dfrac{1}{2}x = 2}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {x = 2 \times 2}$

⠀

$\frak:\implies\: \: \: \: \: \: \: \: {\purple{x = 4}}$

⠀

★ $\small\underline{\sf{Hence,\: the\: required\: number\: is\: 4.}}$
