Answer:
The value of a is 2.
Step-by-step explanation:
First, you have to expand using distributive law :
[tex]4(a + 4) = 2(a + 10)[/tex]
[tex]4a + 16 = 2a + 20[/tex]
Next, you have to move all the common terms to one side :
[tex]4a - 2a = 20 - 16[/tex]
[tex]2a = 4[/tex]
Lastly, you have to solve it by dividing:
[tex]a = 4 \div 2[/tex]
[tex]a = 2[/tex]
