Answer:
s=6 years
m=48 years
Step-by-step explanation:
Let
Mother's age=m
Son's age=s
m=8*s
m=8s (1)
m+6=9/2(s+6)
m+6=9/2s+27 (2)
Substitute (1) into (2)
m+6=9/2(s)+27
8s+6=9/2s+27
8s+6-9/2s-27=0
8s-9/2s-21=0
(16-9/2)s-21=0
7/2s=21
s=21÷7/2
=21×2/7
=42/7
s=6
Present age of the son=6
m=8s
=8(6)
m=48
Present age of the mother=48
Answer:
<h2>11x - 5</h2><h2> or</h2><h2>
x = -5 / 11</h2>
Step-by-step explanation:
3 (2x - 5) + 20 + 5x
= 6x - 15 + 20 + 5x
= 6x + 5x = 15 - 20
= 11x - 5
or if you are looking for x:
then x = -5 / 11
