Question

Solve for x and y : x + 8y = 36, 3x – 2y = 4​

Answer 1

Answer:

x = 4; y = 4;

Step-by-step explanation:

x + 8y = 36; 3x – 2y = 4​

//Multiply equation 3x – 2y = 4​ by 4

4(3x – 2y) = 4*4

12x - 8y = 16;

//Add both the equations

x    + 8y = 36

12x - 8y = 16

------------------

13x = 52

--------------

x = 4;

//substitute value of x in any of the above equations to get y.

x    + 8y = 36

4 + 8y = 36

8y = 36 - 4 = 32

y = 4;
