Answer:

[tex]a = 1/2[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex]3 + 0.5(4a + 8) = 9 - 2a[/tex]

[tex]3 + (0.5 * 4a) + (0.5 * 8) = 9 - 2a[/tex]

[tex]3 + 2a + 4 = 9 - 2a[/tex]

Step 2:  Combine like terms

[tex](3 + 4) + 2a = 9 - 2a[/tex]

[tex]7 + 2a = 9 - 2a[/tex]

Step 3:  Subtract 7 from both sides

[tex]7 + 2a - 7 = 9 - 2a - 7[/tex]

[tex]2a = 2 - 2a[/tex]

Step 4:  Add 2a to both sides

[tex]2a + 2a = 2 - 2a + 2a[/tex]

[tex]4a = 2[/tex]

Step 5:  Divide both sides by 4

[tex]4a / 4 = 2 / 4[/tex]

[tex]a = 1/2[/tex]
