**Question: **Given the system of equations below, solve using any appropriate method:

3x + 6y = 21

-5x + y = 20

0

**Question: **The sum of two numbers is twenty. Using *x* to represent the smaller of the two numbers, translate "the difference between two more than the larger number and twice the smaller number" into a variable expression. Then simplify.

**Question: **Solve: \[3\left[ 4-2\left( x-2 \right) \right]=3\left( 2-4x \right)\]

**Question: **Solve: \[\frac{7}{12}=\frac{2}{3}x+\frac{3}{4}\]

**Question: **Evaluate: \[{{\left( a-4b \right)}^{2}}\div {{c}^{3}}\] when \[a=4,\,\,b=-1,\,\,c=-2\]

**Question: **Simplify: \[3x+8\left( x-4 \right)-3\left( 2x-y \right)\]

**Question: **Simplify: \[5{{x}^{2}}-3x+\left( -2{{x}^{2}} \right)+3x\]

**Question: **A minor league ballpark seats 8000. There are box seats that cost $10, grandstand seats that cost $5 and bleacher seats that are $3 each. When all the seats

are sold, the total revenue is $37,000. The number of bleacher seats is four times the number of box seats. How many of each type of seat are there at the

ballpark? Set up both the equations and matrix.
