Understanding and generating non-linear equations in two or more variables

Solve for y.

• y= m + p

• y= m - p

• y= mp 

• 
• 
• 
• 

• -4= 3x-y 
• 3x-y=-4  
• 3x-y=-1
• 3/4x-1/4y=-1

Solve for p.

 $x=\frac{2y-z}{p}$  

(in your answer: make sure there are no spaces)

• Add 9 to both side

• Subtract 9 from both side

• Multiply 9 to both side

• Divided 9 from both side

 Area of a rectangle is  $A=lw$ . Which equation will find the width of the rectangle?

•  $w=Al$  

•  $w=\frac{A}{l}$  

•  $w=\frac{l}{A}$  

•  $l=\frac{A}{w}$  

Solve for b.
 $16+b^2=c^2$  

•  $b^2=c^2-16$  

•  $b=-16+c$  

•  $c=4+b$  

•  $b=c-4$  

Make w the subject of 
A = lw

• w = A/l
• w = l/A
• w = A - l
• w = Al
