we are doing sloving system of linear equations by substituting
1)y=5x 2x+3y=34 i got (2,10)
2)x=4y 2x+3y=44 i got (16,4)
3)x=4y+5 x=3y2 i got (23,7)
4)y=2x+3 y=4x1 i got (2,7)
5)4c=3d+3 c=d1 i got (6,7)

all correct.

continued
4c=3d+3 c=d1 i got (6,7)
x=1/2y+3 2xy=6 i got no solution
8x+2y=13 4x+y=11 i got no solution
2xy=4 3x+y=9 i got (13,30)
3x5y=11 x3y=1 i got (7,2) 
subtititoin what is number 4y2x=6 and 8y=4x12
