Solve the following polynomial inequalities.
4x - 5 ≤ 2(x - 7)

• math -

4 x - 5 ¡Ü 2( x - 7 )

4 x - 5 ¡Ü 2 * x - 2 * 7

4 x - 5 ¡Ü 2 x - 14 Add - 2 x to both sides

4 x - 2 x - 5 ¡Ü 2 x - 14 - 2 x

2 x - 5 ¡Ü - 14 Add 5 to both sides

2 x - 5 + 5 ¡Ü - 14 + 5

2 x ¡Ü - 9 Divide both sides by 2

x ¡Ü - 9 / 2

• math -

¡Ü

mean less or equal
