Answer: (-3,4) and (9,20)
I think these two points will make the answer you have been looking for.
7n + 12= -23
Subtract 12 from both sides
7n= -35
Divide 7 on both sides
Final Answer: n= -5
The answer for 10x - 2y = 20 is y= 5x - 10
The answer for 5x = y + 10 is y = 5x - 10
so basically from this 5x - 10 is the results and 10x - 2y = 20 and 5x = y + 10 are different problems that lead to the same result, hope this helps
(2.75 + 4.25) / 50 = 7/50 = 0.14 = 14% <==
