Question

What is the solution to the system of equations? 2x – y = 7 y = 2x 3

Answer 1

I will assume the second equation is y=2x^3. If it is y=2x+3 or y=2x-3, the lines will never intersect: they have the same slope (2):

Explanation:

2x – y = 7 can be rewritten as: y = 2x -7. It has a slope of 2. The second equation, y = 2x 3, isn't clearly written. If the 3 has a plus or minus sign, then the lines will never intersect: they have the same slope, 2.

I'll assume the second equation is y=2x^3.
