Heya, here is your answer....
Given,
Equation 1 = 3x-4y = 10.
Equation 2 = 4x+3y = 5.
Let, the equation 1 be multiplied by 3., and the equation 2 be multiplied by 4....
Then, we get,....
Equation 1 = 9x-12y = 30.
Equation 2 = 16x+12y = 20.
Add the equations 1 and 2.....
We get, 25x = 50.
Therefore, we get x = 2..
Now substitute the value of 'x' in equation 1...
We get, 3(2) - 4y =10.
=> 6-4y = 10.
=> 6-10 = 4y
=> - 4 = 4y...
Therefore, y = - 1.
Hence, the answer is x = 2, y = - 1
Hope this helps you...
Thank you....
