Solve. Hint: Remember to use the LCM to get rid of the fractions!

Solve for b.

 $y\ =\ \frac{b+\ 4a}{3x}$  

• b = 3x( y - 4a )

• b = 3xy - 4a

• b = y - 4a

• b =  $\frac{3xy-12ax}{3x}$

Solve for T

 $V\ =\ 8T-RT$  

•  $T\ =\ \frac{V}{\left(8-R\right)}$  

•  $T\ =\ \frac{RT\ -\ V}{8}$  

•  $T\ =\ \frac{\left(8-R\right)}{V}$  

• None of the above

Kobe and Pablo are heading to Arbys to get sandwiches for the crew. Kobe buys 4 roast beef (R) and 3 gyros (G) and spends $30. Pablo buys 2 roast beef and 4 gyros and spends $25. Write a system of equations to represent this food fest.

• 4R + 3G = 25

  2R + 4G = 30

• 4G + 3R = 30

  2G + 4R = 25

• 4R - 3G = 30

  2R - 4G = 25

• 4R + 3G = 30

  2R + 4G = 25

Using technology, solve by graphing. Please write answer in coordinate (x , y) form. Ex: (3,4) for x= 3, y = 4

 $y\ =\ x-1$  

 $y\ =\ \frac{1}{4}x+2$

Solve by using substitution. Please write answer in coordinate form (x,y) Ex: (3,4) is x = 3, y = 4

x = 2y - 6

5x + 2y = -6
