6x+7y=4x+4y complete the missing value in the solution to the equation. )

(6,-4)

Step-by-step explanation:

6x+7y=4x+4y

If (?,-4)

So we are solving for x. Substitute the y with -4.abd solve.

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

Multiply 7(-4) on left side and 4(-4) on right side.

6x-28=4x-16

Subtract 4x both sides to get x term on left side

6x-4x-28= -16

Now add 28 to both sides to move to the right side because you want to keep x on left side.

6x-4x=28-16

2x= 28-16

Subtract 28 from 16

2x= 12

Divide 2 to both sides

X=12/2

Solve 12÷2=6

X=6
