Question

solve the followingsets of simultaneous equations by elimination method..

plz reply if u know answer​

Answer 1

Answer:

2x +y = 5

3x - y = 5

________

5x = 10

or, x= 2

then, putting value of x in one of the eqn.

2×(2)+y = 5

4+y = 5

therefore, y= 1

so, x= 2,y=1

Answer 2

Answer:

x = 2

y = 1

Explanation:

2x + y = 5

3x - y = 5

5x = 10

=> x = 10/5

=> x = 2

Substituting the value of x we get:-

2×2 + y = 5

=> 4 + y = 5

=> y = 5 - 4

=> y = 1
