Question
2x +y = 10 Complete the missing value in the solution to the equation. (……..,- 6 )
- 8
- 2
- 5
- -6
Hint:
Substitute the value of y in the equation and find the missing value.
The correct answer is: 8
Given :
2x +y = 10 and (x,y) = (x, -6)
To find the value of missing variable, substitute the values of known variable in the equation, we get :
2x - 6 = 10
2x = 16
x= 8
Thus, 8 is the missing value to the solution.

We can solve the equation in two variable using elimination method, substitution method and cross multiplication method. In elimination method we can find the solution of the two variables by cancelling one variable by adding, multiplying or subtracting both the equations from which we will get the value of one variable. After getting the value of one variable we can put the value of that variable in equation and get the value of another variable.
