Question

Find using elimination method-:
2x-y=6 x-y=2

Answer 1

Answer:

The required solution are x=4, y=2

1. Step-by-step explanation: 2x-y=6. x-y=2. ⇒x=2+y.

2. Substituting x in 2x-y=6. 2x-y=6. ⇒2(2+y)-y=6. ⇒4+2y-y=6. ⇒4+y=6.

3. Isolate y by subtracting 4 from both sides. ⇒4-4+y=6-4. ⇒y=2.

4. Now substitute the y=2 in x=2+y. x=2+y. ⇒x=2+2. ⇒x=4.
