Question

c) 7>x - 3>- 4, x belongs to R​

Answer 1

Here,

$\rm{}7 > x - 3 > - 4, \: x \in R$

Now,

$\to \: \: \sf{}7 \green> x - 3 \green> - 4 \\ \\ { \underline{\tt{}adding \: \: 3 \: \: at \: \: each \: \: side}} \\ \\ \to \: \: \sf7 + 3 \green> x - 3 + 3 \green> - 4 + 3 \\ \to \: \: \sf10 \green> x \green> - 1$

$\small \therefore \bf \: \: \: x = \{0, \: 1, \: ...... , \: 9\}$
