Question 105772This question is from textbook Principles of Microeconmics
: I need to be able to find the intersection of the 2 lines given the following information.
Line 1: y = 1600 - 300x
Line 2: y = 1400 + 700x
I don't know how to get both y's and both x's to equal without using a graphing calculator and calculating the intersection. i would like to know how to figure this out step by step without a calculator This question is from textbook Principles of Microeconmics

You can put this solution on YOUR website!
In finding the intersections of two lines, we just have to put them into equations.
So:
1600+-+300x+=+1400+%2B+700x
Solving, we have:
200+=+1000x
x+=+1%2F5
THe intersection is at point 1%2F5
THank you.
