Question

3. Solve by the linear combination method (with or without multiplication).

4g + 5h = 4
8g – 10h = 4 (Points : 1)

Answer 1

i solved it but it gave me 0=4

Answer 2

what is the linear combination method

Answer 3

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

Answer 4

solution*

Answer 5

if you multiply the first equation by 2

Answer 6

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

Answer 7

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

Answer 8

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
