Question

How can x2 + 3x + 1 = 2x2 + 2x + 3 be set up as a system of equations?

Answer 1

the answer to this question is

y = x² + 3x + 1

y = 2x² + 2x + 3

Answer 2

The answer is:
y = x² + 3x + 1
y = 2x² + 2x + 3


If a = b = y, then a = y and b = ?
Our expression is x² + 3x + 1 = 2x² + 2x + 3

Let x² + 3x + 1 = 2x² + 2x + 3 = y
Therefore
x² + 3x + 1 = y
2x² + 2x + 3 = y

Now we have the system of two equations:
1. y = x² + 3x + 1
2. y = 2x² + 2x + 3
