will some one help me please will friend

Add the equations,just the way they appear there.
-- Add the top 'x' to the bottom 'x'. Write the sum under the 'x's. -- Add the '+y' and the '-y'. Write the sum under the 'y's. -- Add the '2' and the '4'. Write the sum under them, with n " = " sign before it.
You should now have an equation with only 'x' in it and no 'y'. You can easily solve that one and find out the value of 'x'.
Once you know the value of 'x', go back to either one of the original equations, and plug the number-value of 'x' in place of 'x'.
You'll then have an equation with only 'y' in it and no 'x'. You can easily solve that one and find out the value of 'y'.

To solve simultaneous linear equations, you can use either substitution or elimination methods. Start by expressing one variable in terms of the other and substitute it back into the first equation to find the values of both variables. Finally, verify your solutions by substituting them back into the original equations.
