Question

can someone explain to me solving innequalities useing addition or subtraction using these problems.
v-6<4
q+0.5>-2

Using the first inequality as an example, you need to isolate the variable.  On the left side, you have "v" and "-6" (adding a negative 6"), so you have 2 terms.  You have to remove the "-6" from the left, so ADD 6 to BOTH sides.  Adding or subtracting the same quantity from both sides will preserve the inequality.  Works for equalitites, too.  So, add 6 to each side and see what you get.

oh yay thank you thats the first time ive understood that.

anonymous · Answer

With the second inequality you would use subtraction, and perhaps you can determine what to subtract from both sides.

Here's a little hint:  q + 0.5 > -2     ->      (q + 0.5) - (some specific #) > -2 - (the same some specific #)

anonymous · Answer

q>-2.5
