What you do to the center to make it become only x, you do to all 3.

Given: $5< 4x + 3 <= 11$

What you do to the center to make it become only x, you do to all 3.

Subtract 3:

$2 < 4x <= 8$

Divide by 4:

$1/2< x <= 2$

$1/2< x <=2$

Subtract 3 from both sides:

$color(green)(2)<4x<=color(green)(8)$

Divide 4 from both sides:

$color(green)(2/4)< x <=color(green)(8/4)$

Simplify:

$color(green)(1/2)< x <=color(green)(2)$
