Question

Solve : 3x ty = 5; 2x + 3y = 1​

Answer 1

Answer: x = 2 and y = -1

Step-by-step explanation:

3x + y = 5 ….. (1)

2x - y = 1 …..(2)

Multiply by 3 equation (1) we get,

9x + 3y = 15 ….(3)

Now subtracting equation (2) and (3) we get,

9x + 3y = 15

2x + 3y = 1

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

7x = 14

x = 14/7

x = 2

Substituting x = 2 in (2) we get

2x + 3y = 1

2 x 2 + 3y = 1

4 + 3y = 1

3y = 1 -4

3y = -3

y = -3/3

y = -1

Therefore, x = 2 and y = -1 are the solution of the given equation.
