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

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

The missing value in the solution to the equation is 6

Given the expression 6x+7y=4x+4y

For us to get the x-coordinate of the expression, we will substitute the value of y given into the equation and find the value of y as shown:

6x+7y=4x+4y

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

6x -28 = 4x - 16

6x - 4x = -16 + 28

2x = 12

x = 6

Hence the missing value in the solution to the equation is 6
