Question

if -2x - 3y = 10 and 3x + 2y = 7 find the value of x-y ?​

Answer 1

Answer:

the value of x-y is 17

so,

x-y = 17

Answer 2

Answer:

x= 41/5, y=-39/5

Step-by-step explanation:

We have to use the Elimination method where we have to eliminate one variable.

Here, we will eliminate the variable y.

-2x -3y = 10 - (1)

3x +2y = 7 - (2).

Multiply (1) by 2 to get -4x -6y =20.

Multiply (2) by 3 to get 9x +6y =21

Now, (1)+(2),

-4x -6y +9x +6 y = 20+21

5x = 41

x = 41/5.

Put x = 41/5 in (1) to get y = -39/5.

x-y = 16

Hope this helps you.
