Answer:

b = 5

Step-by-step explanation:

Solving

Step 1: Plug in the values of a and c.

  • [tex]\frac{1+b+2}{4} =2[/tex]

Step 2: Combine like terms on both sides.

  • [tex]\frac{(2+1)+b}{4}=2[/tex]
  • [tex]\frac{3+b}{4}=2[/tex]

Step 3: Multiply both sides by 4.

  • [tex]\frac{3+b}{4} *4 = 2*4[/tex]
  • [tex]3+b=8[/tex]

Step 4: Subtract 3 from both sides.

  • [tex]3+b-3=8-3[/tex]
  • [tex]b=5[/tex]

Step 5: Check if solution is correct.

  • [tex]\frac{1+5+2}{4} = 2[/tex]
  • [tex]\frac{8}{4} =2[/tex]
  • [tex]2=2[/tex]

Have a lovely rest of your day/night, and good luck with your assignments! ♡
