Question
In natural numbers, $4x + 5 = -7$ has ________ solution.
✓
Answer
Solve thr equation for $x,$
$4x + 5 = -7$
$\Rightarrow 4x = -7 - 5 [$transposing $5$ to $RHS]$
$\Rightarrow 4x = -12$
$\Rightarrow x = -3 [$dividing both sides by $3]$
Since, the value of $x$ is not natural number, hence the equation has no solution in natural numbers.
