Question

the pair of linear equations 2x-3y=1 and 3x-2y=5 have how much solutions

Answer 1

Step-by-step explanation:

2x -3y = 1.......(1)

3x -2y = 5.......(2)

Has 2 solns

1 soln of x

and 1 of y

Let's add (1)&(2)

5x - 5y = 6........(3)

now subtract (1)&(2)

-x -y = -4

x +y = 4........(4)

multiply (4) by 5

5x +5y = 20.......(5)

Now solve (3)&(5)

5x -5y = 6

5x + 5y = 20

_______________

10x = 26

x = 2.6

x = 2.6y = 7

Hope it helps uh!!
