Answer:
The missing value in the solution to the equation is 6.
So, the complete solution is (6, -4).
Step-by-step explanation:
Given:
6x+7y=4x+4y.
( ,-4)
Now, to complete the missing value in the solution to the equation.
As, the equation is:
[tex]6x+7y=4x+4y[/tex]
And, the solution is:
[tex](x,y)=(\ \ ,-4)[/tex]
Now, solving the equation by putting the value of [tex]y=-4[/tex] :
[tex]6x+7(-4)=4x+4(-4)\\\\6x+(-28)=4x+(-16)\\\\6x-28=4x-16\\\\[/tex]
Adding both sides by 28 we get:
[tex]6x=4x+12[/tex]
Subtracting both sides by [tex]4x[/tex] we get:
[tex]2x=12[/tex]
Dividing both sides by 2 we get:
[tex]x=6.[/tex]
Thus, the solution to the equation is (6, -4).
Therefore, the missing value in the solution to the equation is 6.
