Solving equations with multiple variables

Literal Equations

An equation with more than one variable

The goal is to isolate the given variable using the same steps to solve equations

(reverse/opposite operations to move a term to the other side)

Solve for r

• Since r and t are stuck together it is multiplication

• To move the t you need to divide both sides by t

Multiple Choice

Solve for c

• $A\ -\ b\ =\ c$
  

• $A\ \cdot\ b\ =\ c$
  

• $A\ +\ b\ =\ c$
  

• $\frac{A}{b}=\ c$

Solve for c

• Since b and c are stuck together it is multiplication

• Divide both sides by b to get A/b = c

Multiple Choice

Solve for m

•  $m\ =\ e\ \cdot\ g$ 
  

•  $m\ =\ \frac{e}{g}$ 
  

•  $m\ =\ e\ -\ g$ 
  

•  $m\ =\ e\ +\ g$ 

Solve for b

• Since it is subtracting w you need to add w to both sides to create the zero pair and cancel it out

• If it was b + w then you would do the opposite by subtracting

Multiple Choice

Solve for S

•  $h\ -\ n\ =\ S$  
  

•  $\frac{h}{n}=\ S$  
  

•  $h\ +\ n\ =\ S$  
  

•  $h\ \cdot\ n\ =\ S$
