Question

3x + 5y =7
-4x + 5y = 14.
please help me

Answer 1

Answer:

x = -1

y = 2

Step-by-step explanation:

3x + 5y =7 -----------1

-4x + 5y = 14 --------2

On subtracting equation 2 from 1,

3x + 5y =7

-(-4x + 5y = 14)

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

7x. = -7

x = -1

Now putting value of x in equation 1,

3(-1)+ 5y = 7

5y = 7 + 3

5y = 10

y = 2

Hope it helps ☺☺️
