Answer:

The solution of the system can be given as (5,-8).
Step-by-step explanation:
Given system of equations:


To solve the given system of equations:
Solution:
We will use substitution to solve the given system.
We will substitute the
values in terms of
from the equation
into the other equation to solve for 
Substituting
into
.
We have:

<em>Using distribution.</em>

<em>Combining like terms.</em>

Adding 6 both sides.


Dividing both sides by 3.

∴ 
<em>Plugging in
into
.</em>
We have,

∴ 
The solution of the system can be given as (5,-8).
.28 if 1 was 100,and .28 was 2.8, then we divide 100 by 100 same for 2.8
A) 3:11
b) 11:8
this should be correct
Oh ok!
How many tens are in 100? =10
so, 10 * 5 = 50
Now, 50 + 4 = 54!
Hope so now i get it correct!
