3x + 5
\geq 7
Subtract 5 to both sides so
3x + 5 - 5
\geq 7 - 5
3x
\geq 2
Divide 3 to both sides
3x
\geq 2

(3x)/(3) \geq (2)/(3)
Cancel out the 3 on the left side,

(2)/(3) = (3)/(2)

x \geq 4

3x+5>_7
Subtract 5 on both sides

3x+5>_7
-5 -5

3x>_2

Divide 3 on both sides to solve for x
You get:
x>_2/3
