You must get the like terms on the correct sides, so here is how to solve it:
First subtract 5x from both sides: 3x+4=-11
Then subtract 4 from both sides: 3x=-15
Finally divide by 3: x=-5
Answer:
True

Answer:
3^-x= 3^ 3x + 6
Step-by-step explanation:
match bases
remeber if a^b=a^c where a=a then b=c
remember
(x^m)^n=x^(mn)
1/(x^m)=x^-m
base of 3
(1/3)^x=(3^-1)^x=3^(-x)
27^(x+2)=(3^3)^(x+2)=3^(3x+6)
3^(-x)=3^(3x+6)
-x=3x+6
0=4x+6
-6=4x
-3/2=x
<span>h/9 = 7
multiply both sides by 9
h/9 x 9 = 7 x 9
h = 63</span>
