Question 142807
The hardest part about these problems is getting from words to numbers. 

15 > x - 7... is the equation I get. The phrase "15 is" tells me automatically to put "15=" no exceptions...well in this case the = sign is the greater than sign(>). And when they say " a number" you can just put in any old letter, I like x.

Add 7 to both sides. you get:

......22 > x 

x + 11 <= 9... is what I get for the second problem( <= is less than or equal to). Again I see that word "is", "is" always acts as the = sign (or >, <, <=).

Subtract 11 from both sides. You get:

.......x <= -2

Some basic rules to follow when working with word problems:
..."A number" = x
..."is" = (=, <, >, >=)
