Solving Equations and Inequalities

Solve the following inequality  $-2x+5<13$  

•  $x\ge-4$  
  

•  $x>4$  

•  $x<4$  

•  $x>-4$  

When multiplying or dividing by a negative number, what must you do with your inequality symbol?

• Change it to an equal sign

Which statement best describes the first step to the equation?  $8m+11=-53$  

• Add 11 to both sides

• Add 53 on both sides

• Subtract 11 on both sides

• Divide 8 on both sides

 $8\left(5+w\right)-5$  

Simplify the following expression.

•  $8w+35$  

•  $w\ -\ 45$  

•  $8w+40$  

•  $w\ -35$  

The steps in solving $5b\ -6=24$  are to...

• Add 6 to both sides the divide both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

 $30=8-2x$
