Answer:
3a -12
Step-by-step explanation:
3(– 2а - 4) + За → -6a - 12 + 3a → -3a -12
When no base is stated, assume base 10
and

translates to

g(x)=1, hmm
1=1.1845-log x
times -1 both sides
-1=log x-1.1845
add 1.1845 to both sides
0.1845=log x
translate and assume base 10

that's the exact value of x such that g(x)=1
you can evaluate it yourself
