Pls help this is due tmrw and i actually suck at math Solve the following system of equations using substitution. Show ALL of your work and write the ordered pair in the space provided. y = x - 1 y = 2x + 1

substitution method would go as follows

5x-2=7x-8 we than rearange it so it becomes 5x-7x=-8-2 this than becomes -2x=-6 so x=3

we can than substitute 3 for x in one of the first equations

y=7 times 3-8 = 21-8 = 13

so therfore the interception should be at 3,13

Step-by-step explanation:

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.
