Solve:

3x - y = 11

x + y = 5

• x = 4

  y = 1

• x = -4

  y = 1

• x = 4

  y = -1

• x = -4

  y = -1

Solve:

2x + 3y = 5

x + 3y = 7

• x = -2

  y = 3

• x = 2

  y = -3

• x = -2

  y = -3

• x = 2

  y = 3

Christian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of colour 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 colour brochures. Which simultaneous equations represent this situation?

• x+y=134

  x+y=120

• 3x+3y=134

  4x+3y=120

• 4x+3y=134

  3x+3y=120

• 7xy=134

  6xy=120

Two pencils and a ruler cost 49 cents in total. One pencil and two rulers cost 62 cents in total. Write the two simultaneous equations to represent this info.

• -2x+y=49

  -x+2y=62

• 2x+y=49

  x+2y=62

• 2x+y=62

  x+2y=49

• 2x-y=49

  x-2y=62
