Question
Solve the pair of linear equations,
Also find p if p = 2x + 3
Hint:
find x by eliminating y and find y by substituting x in the equations .
The correct answer is: x = 2 ; y = 0 ; p = 7
Ans :- x = 2 ; y = 0 ; p = 7
Explanation :-

Step 1 :- Find x by eliminating y .
Adding eq1 and eq2



Step 2:- substitute x = 2 in eq 1 to get y



Step 3:- calculate P
Given p = 2x + 3


is the solution to the equation and value of p = 7

Which of the following could be the x-coordinate of a solution to the system of equations above?
Note:
If we had to find the y-coordinate of the system of equations, then we put this value of x in the equation to get the value of y. Here, we got a quadratic equation of x, which did not have any term containing x, so it was easier to solve. If the quadratic equation was of the form
, then we would use the quadratic formula
to solve the equation.
