$(1)/(2) x - 4 < 3 \\$

Add both sides 4

$(1)/(2) x - 4 + 4 < 3 + 4 \\$

$(1)/(2) x < 7 \\$

Multiply both sides by 2

$2 * (1)/(2) x < 2 * 7 \\$

x < 14

_____________________________________________

$7 \leqslant 3x + 5$

$3x + 5 \geqslant 7$

Subtract both sides minus 5

$3x + 5 - 5 \geqslant 7 - 5$

$3x \geqslant 2$

Divide both sides by 3

$(3x)/(3) \geqslant (2)/(3) \\$

$x \geqslant (2)/(3) \\$
