Consider the following system of equations:

2x + 3y = 45
x+y = 10
what is the x-value of the solution for this system?

x=-15, y=25. (-15, 25).

Step-by-step explanation:

2x+3y=45

x+y=10

x=10-y

2(10-y)+3y=45

20-2y+3y=45

20+y=45

y=45-20

y=25

x+25=10

x=10-25

x=-15

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
