Question

# Use Substitution to solve each system of equations :

2X + 2Y = 6

4X + 4Y = 4

Hint:

### find y by substituting x (in terms of y) in the equation and find x by substituting the value of y in the equations .If we get an true statement we say they have infinite solutions .If we get the false statement we say they have no solution.

## The correct answer is: They have no solution for the given system of equations.

### Ans :-no solution.

Explanation :-

— eq 1

—- eq 2

Step 1 :- find y by substituting in eq 2.

12 = 4

Here we get 12 = 4 which is always false i.e solutions do not exist

They are parallel with each other and have no solutions

They have no solution for the given system of equations.
