Christian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of color brochures, which cost a total of $134. After those ran out, Christian spent $120 on 3 boxes of black-and-white brochures and 3 boxes of color brochures. Which system represents this situation?

• x+y=134
  x+y=120

• 3x+3y=134
  4x+3y=120

• 4x+3y=134
  3x+3y=120

• 7xy=134
  6xy=120

Write the solution to this system of equations as a coordinate pair, (x,y) with no spaces

7x + 2y = -5

-7x + 5y = 12

Write the solution to this system of equations using a coordinate pair, (x,y), with no spaces.

y = -4x

-2x + y = -6

Solve the system:

2x+y= -1

-4x+6y=42

Solve the following systems of equations using substitution:

y = 3 - x

3y + x = 5

• No solution

• (1, 2)

• (3, 0)

• (2, 1)

On the Graph Paper provided, graph the system of equations and find the solution.

y = -3x + 2

y = 2x - 3

• (-1, 1)

• (1, -1)

• (-5, -13)

• No Solution

On the Graph Paper

y = -1/2x + 4

y = -1/2x - 6

• (10, -1)

• (4, -4)

• No Solution
