Question 1102924: Where do the lines y=35x and y=15x+2000 meet?

You can put this solution on YOUR website!
35x=15x%2B2000
Solve that and use it to determine the y-value.

Both equations are given as formulas for y. Where the two LINES of the equations meet, the two values for y must be equal; meaning the expressions for y must be equal.

35x=y=15x%2B2000
NOW solve this for x.

What y value will correspond to the found x value?
Now you have the (x,y) intersection point.

You should be able to find x=100. Now use this to find what is y.
