Question

How many solutions does the following system of equations have?
y=5/2x+2
2y= 5x +4

Answer 1

infinite solutions

Explanation:

y=5/2x+2

2y= 5x +4

Multiply the first equation by 2

y = 5/2 x +2

2y = 5/2 *2 x +2 *2

2y = 5x +4

Since this is identical to the second equation (they are the same), the system of equations has infinite solutions
