 $2\left(2x+13\right)\ge4\left(-6+x\right)$  

•  $x\ge-6.25$  

• Infinitely Many Solutions

• No Solution

•  $x\le0$  

 $2h+11>-7+4h-16$  

•  $h<17$  

•  $h<6$  

•  $h>-17$  

•  $h>-6$  

What is the FIRST step to solving this inequality?

 $-4\left(x-9\right)+2x\ge-27$  

• Subtract 2x on both sides

• Distribute: multiply -4 by x and by -9

• Add x to 2x

• Add 9 to both sides
