we have

6x+7y=4x+4y

we know that

the solution is ----> (x,-4)

substitute the value of y=-4 in the equation

6x+7*(-4)=4x+4*(-4)

6x-28=4x-16

Combine like terms

6x-4x=28-16

2x=12

x=12/2

x=6

therefore

the answer is

the missing value is x=6

Direct variation is y=kx, so you have to put those numbers and find the constant. Once you have done that, use the other number to find the answer
