Solve the system by substitution y=6x and 7x-8y=-41

Y=6 and x=1

Step-by-step explanation:

y=6x

∴y-6x=0

and 7x-8y=-41

Suppose,

-6x+y=0→(1)

and 7x-8y=-41→(2)

Taking equation (1), we have

-6x+y=0

⇒y=6x→(3)

Putting y=6x in equation (2), we get

7x-8y=-41

7x-8(6x)=-41

⇒7x-48x=-41

⇒-41x=-41

⇒x=1→(4)

Now, Putting x=1 in equation (3), we get

y=6x

⇒y=6(1)

⇒y=6

∴y=6 and x=1

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
