<h3> Number = 23</h3>
<h2>Step-by-step explanation:</h2>
<h3>Given:</h3>
Six is subtracted from a number.
The result is equal to one fourth of the sum of the number and 45 find the number .
<h3 /><h3>To Find:</h3>
What is the number ?
Solution: Let the number be x.
➟ Subtracting 6 from x.
➟ (x – 6) ㅤㅤㅤㅤㅤ(eqⁿ 1)
Now,
➙ One fourth of sum of the number + 45
➙ 1/4 × x + 45
➙ x + 45/4ㅤㅤㅤㅤ(eqⁿ 2)
According to the question,
Equation 1 = 2
⟹ (x – 6) = x + 45/4
⟹ 4(x – 6) = x + 45
⟹ 4x – 24 = x + 45
⟹ 4x – x = 45 + 24
⟹ 3x = 69
⟹ x = 69/3
⟹ x =23
Hence, the number is 23.
