Step-by-step explanation:
8x+ 14y= 4
-6×-7y= -10
For elimination method we can decide to eliminate either the y or x variable I'm going to eliminate the x variable so either of the one am eliminating we multiply the first equation by the coefficient of the variable we are eliminating in other words
8x +14y=4.....*-6
-6×-7y= -10......*8
-48x-84y= -24
-48x-56y= 80
then we multiply the second equation all through by -1
-48x-84y= -24
48x+ 56y= -80
28y=-104
y= 26/7
x= 8/3
