Answer:
-2
Explanation:
first you distribute
12-4a-8a-48-7=14a-7+16
Then cancel equal terms on both sides of the equation
12-4a-8a-48=14a+16
Next, you combine like terms
-36-4a-8a=14a+16
-36-12a=14a+16
Move 14a by subtracting from both sides
-36-12a-14a=16
And add 36 to both sides
-12a-14a=16+36
Combine like terms again
-26a=52
Divide both sides by -26
a=-2
