Question

How many solutions does this linear system have?
Y=2x-5
-8-4y=-20

Answer 1

Infinite number of solutions.

Explanation:

/ Solve equation [1] for the variable y

[1] y = 2x - 5

// Plug this in for variable y in equation [2]

[2] -4•(2x-5) + 8x = 20

[2] 0 = 0 => Infinitely many solutions

Infinitely many solutions
