|dw:1350454728404:dw| did you mean this?
nop
4x-3|<7 what does that line mean
egnor the line my mistake
4x-3<7 you want to isolate x to do this you want to get all x terms to one side and all constants to the other side so you have 4x-3<7 you want to get the 3 on the right side, to do this you will do the opposite of the sign it has so you have -3, do the opposite, what do you get?
um ....4?
no... you have a -3 the opposite would be +3, +3 to both sides this gives 4x-3+3<7 +3 simplify this
4x-9<10
you got the 10 right, but if you do -3+3 this goes to 0 this is because you are adding, you multiplied so 4x-3+3<10 4x<10
now you have 4x you want x to get x on it's own you must do the opposite, so since it is 4 multiplied by x, you will divide by 4 what do you get?
