Y=-x+7 , y=x-1 and show your work Help !
1 answer:
This is a system of equations. The best way to solve it is by realizing that you have two equations equal to y. Since y = y, it follows that 
. Solving for x, you get 4.
Then, substitute 4 into one of the original equations to find y.
.
The solution is
. I have attached a graphical representation of the solution as well.
Then, substitute 4 into one of the original equations to find y.
The solution is

Answer:
x=14, x=1
Step-by-step explanation:
View Image.
First factor the equation. Which numbers multiplies to 14 and adds up to -15? It's -14 and -1 so the equation is factored to (x-14)(x-1). I assume that you know how to do this.
Then set the values inside the parentheses equal to 0 and solve for x.
