Q:

Classify each system of equations as having a single solution, no solution, or infinite solutions.(y = 5 - 2x4x + 2y = 10)(x = 26 - 3y2x + 6y = 22)(5x + 4y = 610x – 2y = 7)(x + 2y = 34x + 8y = 15)(3x + 4y = 17-6x = 10y - 39)(x + 5y = 245x = 12 - y)

Accepted Solution

A:
Answer: y=mx+b solution!Step-by-step explanation: y = 5 - 2x right?So that's correct and needs no change.But 4x + 2y = 10 needs to be changed!4x + 2y =10-4x          -4x2y = -4x + 10__     __   __ 2       2     2y = -2x + 5
