You can solve by subtracting: 500-330
but I like to use mental math and think this way:
she has 330
70 more will give her 400
and 100 more will give her 500
100 + 70 is 170.
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).
Given:
Original point (2, -2)
Scale factor (k) = 5
Center = origin = (0, 0)
To find:
The image of (2, -2)
Solution:
Let
be the original point and
be the image of the point.
Image of the point is obtained by multiplying original point by scale factor.

Substitute the given values:



The image of (2, -2) after dilation is (10, -10).
