dybincka [34]

Answer:

(5, -1) and (10, 2)

Step-by-step explanation:

*For (5,y)

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>5</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>?</em>

3x-5y=20

3×5-5y=20

15-5y=20

-5y=20-15

-5y=5

y= 5/-5

y= -1

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>5</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>-1</em><em> </em>

<em>(</em><em>5</em><em>,</em><em>-1</em><em>)</em>

*For (x,2)

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>?</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>2</em>

3x-5y=20

3x-5×2=20

3x-10=20

3x=20+10

3x=30

x=30/3

x=10

<em>When</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>1</em><em>0</em><em>,</em><em> </em><em>y</em><em> </em><em>is</em><em> </em><em>2</em>

<em>(</em><em>1</em><em>0</em><em>,</em><em>2</em><em>)</em>
