If $7x + 4 = 25,$ then $x$ is equal to:
  • A
    $\frac{29}{7}$
  • B
    $\frac{100}{7}$
  • C
    $2$
  • ✓
    $3$
✓

Correct option: D.
$3$

 Given equation is $7x + 4 = 25$
$⇒ 7x = 25 - 4 [$transposing $4$ to $RHS]$
$⇒ 7x = 21$
On dividing the above equation by $7,$ we get
$x = 3$
Hence, the solution of the given equation is $3.$
