Question:

If 3x + 7 = 28, find x.

यदि 3x + 7 = 28 है, तो x का मान ज्ञात कीजिए।

Options:

  • a) 7
  • b) 6
  • c) 5
  • d) 8
  • a) 7
  • b) 6
  • c) 5
  • d) 8

correct answer : a)

Explanation:

Given equation: $3x + 7 = 28$
Subtract 7 from both sides: $3x = 28 – 7$
$3x = 21$
Divide by 3: $x = \frac{21}{3} = 7$.

दिया गया समीकरण: $3x + 7 = 28$
दोनों पक्षों से 7 घटाने पर: $3x = 28 – 7$
$3x = 21$
3 से भाग देने पर: $x = \frac{21}{3} = 7$।
