Answer:
x = 2
Step-by-step explanation:
(16 =
and 8 =
)

Since the base number is 2, the exponents must equal each other.
So:
12x = 3x+18
9x = 18
x = 2
If R is between Q and S then QR+RS=QS
given
QR=x+4
RS=3x-1
and QS=27
x+4+3x-1=27
combine like terms
4x+3=27
minus 3 both sides
4x=24
divide both sides by 4
x=6
sub back
QR=x+4
QR=6+4
QR=10
RS=3x-1
RS=3(6)-1
RS=18-1
RS=17
x=6
QR=10
RS=17
