One number is twice another number.
The larger number is 6 less than three
times the smaller number. Find the
two numbers.

Respuesta :


20 and 14


Explanation:
Let the larger number be
x

Then the smaller number will be
x

6

Three times the smaller number is
3
(
x

6
)
, which is equal to two more than twice the other number which is
2
x
+
2

So,

3
(
x

6
)
=
2
x
+
2

Use the distributive property
a
(
b
+
c
)
=
a
b
+
a
c


3
x

18
=
2
x
+
2

Add
18
both sides

3
x
=
2
x
+
20

Subtract
2
x
both sides

x
=
20

We know that the larger number is
20

So, the smaller number is
20

6
=
14
