Translate and solve the algebriac equation.

One-fifth of a number equals 25.

 $16\ =\frac{k}{11}$  

The variable, k, is being divided by 11. What step needs to be completed to isolate the variable k?

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

Solve for y:

 $\frac{3}{-4}y\ =\ 18$  

•  $y=24$  

•  $y=-24$  

•  $y=-\frac{27}{2}$  

•  $y=-72$
