How to know if a system is dependent or independent

Asked by admin @ 23/11/2021 in Mathematics viewed by 251 People

Determine whether the following system of equations is consistent or inconsistent and dependent or independent. y=1/2x+2 -x+2y=4

Answered by admin @ 23/11/2021

Step-by-step explanation:

y=1/2X +2 ,-X +2y= 4

2( y=1/2x +2)

2y= x+2

-x =x +2-4

-2x=-2

x=1 #

-1+2y=4

2y=4+1

2y=5

y=5/2

y=2.0
