Question

Write any two linear equations in two variables x and y whose solution is x = 15 ; y = 10​

Answer 1

Two linear equations in two variables satisfying x = 15 and y = 10.

1. x + 2y - 35 = 0
2. x = 2y - 5.

If you assumed that you do not know the value of x and y, by looking these two equations you can find the values in ease, by:-

1. Graphical method (drawing graphs and getting the values of x, and y at the common intersection point).
2. Substitution method (solve the equation in terms of single varible).
3. Elimination method (multiply the linear equations such that either coefficient y or x becomes same and subtract).
4. Cross multiplication method.
