Answer:
Mr. Gilliam is 49 years old
Step-by-step explanation:
Let Ms. Gilliam = w
Let Mr. Gilliam = w + 3
w + w + 3 =95
2w +3 =95
2w = 95 -3
2w = 92
w = 92/2
w = 46
Mr. Gilliam = 46 + 3
Mr. Gilliam is 49 years old
Answer: spaced it out to make it more clear lol ♀️
Step-by-step explanation:
Explanation:
Let's make Mr Gilliam's age
g
and his wife's age
w
.
From your question, we can understand that
g
is 3 less than
w
.
In equation form, this can be written as:
g
+
3
=
w
or
g
=
w
−
3
So far so clear?
Next, we know that the sum of
g
and
w
is 95.
In equation form, this will be written as:
g
+
w
=
95
Now, here's the trick. You need a change in perspective.
We know that
g
+
3
=
w
and
g
+
w
=
95
, right?
Therefore,
g
+
w
=
95
can also be written as
g
+
(
g
+
3
)
=
95
.
Does that make sense?
If it does, then the equation will become:
2
g
+
3
=
95
(because you had two
g
s)
After shifting the numbers around a little as below, you will arrive at the answer:
2
g
+
3
−
3
=
95
−
3
2
g
=
92
2
g
2
=
92
2
g
=
46
Therefore, Mr. Gilliam is 46 years old. I hope this helps!
