Respuesta :
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
