solving literal equations

A - B = C

(solve for A)

• A = C - B
• A = C + B
• A - C = B
• B = A - C

 $Solve\ 3b=6v-3b,\ for\ b.$  

•  $6b-6$  

•  $b-6$  

•  $0$  

•  $6$  

A - B = C

(solve for A)

• A = C - B
• A = C + B
• A - C = B
• B = A - C

IR = V

(solve for R)

Solve for x:

 $g=6x$  

•  $x=\frac{g}{6}$  

•  $x=\frac{6}{x}$  

•  $x=6g$  

•  $x=g6$  

 $Given\ xy\ +\ w\ =\ 9,\ solve\ for\ y.$  

•  $y=\frac{9+w}{x}$  

•  $y=\frac{9-x}{w}$  

•  $y=\frac{9-w}{x}$  

•  $y=\frac{9+x}{wy}$  

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Solve for a:

 $a-c=d-r$  

•  $a=\frac{d-r}{c}$  

•  $a=d-r+c$  

•  $a=\frac{c}{d-r}$  

•  $a=cdr$
