Multi-Step Equations

 $2x-3+4x=27$  

• 12

• 4

• 5

• 15

 $12\ +5w-4w=15$  

•  $w=1$  

•  $w=5$  

•  $w=3$  

•  $w=-4$  

 $16=\frac{k}{11}$   

Which choice describes the step needed to isolate the variable? 

• Divide both sides by 11

• Multiply both sides by 11

• Add 11 to both sides

• Subtract 11 to both sides

 $\frac{1}{2}x-5=25$  

• 55

• 35

• 15

• 60

 $3y\ +6\ +4y-7=-8$  
Combine like terms and solve for the variable (y)

•  $y\ =-1$  

•  $y=-8$  

•  $y=1$  

•  $y=7$
