You can put this solution on YOUR website!
-7+%3C=+-2x%2B3+%3C=+9
.
You can look at this as two separate equations:
-7+%3C=+-2x%2B3
-2x%2B3+%3C=+9
.
Solving the first one:
-7+%3C=+-2x%2B3
-10+%3C=+-2x
5+%3E=+x
.
Solving the second one:
-2x%2B3+%3C=+9
-2x+%3C=+6
x+%3E=+-3
.
Putting all back together:
-3+%3C=+x+%3C=+5
