Answer:
<h3>The missing value in the given solution is x=6</h3><h3>Therefore the solution is (6,-4)</h3>
Step-by-step explanation:
Given equation is 
<h3>To find the missing value in the solution to the equation :</h3>
- Let missing value in the solution be x
- Then the solution of the given equation is (x,-4)
Substitute the value of y=-4 in the given equation (1) we get



( adding the like terms )



Therefore x=6
<h3>Therefore the missing value in the given solution is x=6</h3><h3>Therefore the solution is (6,-4)</h3>
