Answer:
12
Step-by-step explanation:
Let's write this into a equation:
a - 8 equals is: [tex]a-8=[/tex]
four plus 3 times a is: [tex]4+3a[/tex]
Combining it together we get:
[tex]a-8=4+3a[/tex]
If we subtract 3a from both sides we get:
[tex]-2a-8=4[/tex]
Now we add 8 to both sides to get:
[tex]-2a=12[/tex]
Normally, we would divide both sides by -2 to solve for a, but the question wants us to get the value of -2a, which is 12.
