1)

  • 2x + 1 = 6x -11
  • 6x-2x = 1 + 11
  • 4x = 12
  • x = 3
  • y = 2x + 1
  • y = 2(3) + 1
  • y = 7

2)

  • 3x + 5 = 5x - 5
  • 3x - 5x = -5-5
  • -2x = -10
  • x = 5
  • y = 3x +5
  • y = 3(5) + 5
  • y = 20

3)

  • 4x - 2 = x + 10
  • 3x = 12
  • x = 4
  • y = 4x - 2
  • y = 4(4)-2
  • y = 14

4)

  • 7x - 5 = 3x + 3
  • 7x - 3x = 3 + 5
  • 4x = 8
  • x = 2
  • y = 3x + 3
  • y = 3(2)+3
  • y = 9

5)

  • -2x + 4 = -3x + 5
  • -2x + 3x = 5 - 4
  • x = 1
  • y = -2x + 4
  • y = -2(1) +4
  • y = 2

6)

  • -5x - 3 = 4x + 15
  • -5x - 4x = 15 + 3
  • -9x = 18
  • x = -2
  • y = 4x + 15
  • y = 4(-2) + 15
  • y = 7

7)

  • -x + 7 =2x-11
  • -3x = -18
  • x = 6
  • y = -x + 7
  • y = -6 + 7
  • y = 1

8)

  • 6x - 2 = -2x + 14
  • 8x = 16
  • x = 2
  • y = 6x -2
  • y = 6(2) - 2
  • y = 10
