i solved it but it gave me 0=4

perl · Answer

what is the linear combination method

thefluffmuncher · Answer

i their is not option that says it has no soultion am i doing something wrong

thefluffmuncher · Answer

solution*

perl · Answer

if you multiply the first equation by 2

perl · Answer

4g + 5h = 4 
8g - 10h = 4 

multiply first equation by 2
8g + 10h = 8
8g -10h = 4 

add the two equations
16g = 12
g= 12/16= 3/4

thefluffmuncher · Answer

maybe it came out wrong because i multiplied it by a negative 2

perl · Answer

4g + 5h = 4 
8g - 10h = 4 

multiply first equation by -2
-8g -10h = -8
8g -10h = 4 

add the two equations
-20h = -4
h= 4/20= 1/5
