its substitution method

Answer 3

x-4y=0
+4y +4y
x=4y
3(4y)+5y=0
12y+5y=0
17y=0
divide each side by 17
y=0

Answer 4

x=4y
x=4(0)
x=0

Answer 5

thank you

Answer 6

could you help me with more questions??

Answer 7

4k+m=9
3k-4m=2

Answer 8

yep one sec

Answer 9

4k+m=9
-4k -4k
m=-4k+9
3k-4(-4k+9)=2
3k+16k-36=2
+36 +36
19k=38
divide each side by 19
k=2

Answer 10

4(2)+m=9
8+m=9
-8 -8
m=1

Answer 11

Do you understand what I did to get those answers or would you like me to explain?
