Answer: ( 10 , 2 )
Step-by-step explanation:
You have to put coordinates of each graph on these equations –2x + 5y = –10 and –3x + 5y = –20. If putting coordinates satisfies both equations, then that will be the solution.
For example, lets try value ( 10, 2 )
–2x + 5y = –10
–2×10 + 5×2 = –10
–20 + 10 = –10
–10 = –10, true
–3x + 5y = –20
–3×10 + 5×2 = –20
–30 + 10 = –20
–20 = –20, true
So, ( 10, 2 ) is the solution.
