Unit 3 Replacement Assignment

solve for y

 $2y=8x$  

•  $y=x$ 

•  $y=x+4$  

•  $y=4x$  

•  $y=\frac{1}{4}x$  
  

solve for y

 $4x+6=2y$  

•  $y=2x+3$ 

•  $y=x+4$  

•  $y=\frac{1}{2}x-\frac{3}{2}$  

•  $y=x$  
  

Solve for y

 $\frac{y}{3}-4=5x$  

•  $y=15x+12$  

•  $y=2x-4$  

•  $y=\frac{1}{3}x+7$  

•  $y=5x+10$
