4-3x%3Ex%2B6
Casi todos las mismas leyes como ecuaciones

Additive Inverse of x:
4-3x-x%3Ex%2B6-x

Commutative Property of Addition and combine like-terms of x:
4-4x%3Ex-x%2B6

Additive Inverse Property:
4-4x%3E0%2B6
4-4x%3E6

Additive Inverse of 4:
4-4x-4%3E6-4
-4x%3E2

Multiplicar los dos miembros por -1 cambia la direcction de la desiqualidad:
%28-4x%29%28-1%29%3C2%28-1%29
4x%3C-2

Multiplication Property of inequality using multiplicative inverse of 4:
%281%2F4%294x%3C%281%2F4%29%28-2%29
highlight%28x%3C-1%2F2%29
