In order to eliminate the y terms, the y terms must be reciprocals.
The first equation has 9y.
To eliminate y, you need to add to it -9y.
The second equation has y. In order for the second equation to have -9y, you must multiply both sides of the second equation by -9.

Answer:
The man has 6 GHc20.00 notes and 4 GHc10.00 left
Step-by-step explanation:
Given
Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00
Spendings = GH¢80,00
Required
Determine how many GH¢20.00 and GH¢10.00 notes left
The amount he has can be represented as:


This can be represented as:

Represent:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
So, we have:





Subtract the spendings from the total to get amount left


Collect Like Terms


Recall that, we have represented:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
<em>This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left</em>
B (1,0). -2 + 3 = 1. -2 + 2 = 0.
