Answer:

B.

  1. x= 16
  2. x= 31/3
  3. x= 4
  4. x= 9

C.

  1. Possible values
  • x¹= 9
  • x²= 10
  • x³= 11

2. Possible values

  • x¹= 5/4
  • x²= 1
  • x³= 5/6

Step-by-step explanation:

B.

  1. x+2=18
  • x= 18-2
  • x= 16

2. 3x-5= 26

  • 3x= 26+5
  • 3x/3= 31/3
  • x= 31/3

3. 5x= 20

  • 5x/5= 20/5
  • x= 4

4. 2(x-3)= 12

  • 2x-6= 12
  • 2x= 12+6
  • 2x= 18
  • 2x/2= 18/2
  • x= 9

C.

  1. x+2> 10
  • x+2 -2>10-2

Solut'n: x>8

2. 3x-1< 4

  • 3x-1 +1< 4+1
  • 3x/3< 5/3

Solut'n: x< 5/3
