Question

Solve : x + y = 5 and 2x + y = 10

Answer 1

Answer:

Step-by-step explanation:

2x + y = 5

3x - y = 10

By solving this equation by eliminating method +y and -y would get canceled, leaving -

2x + 3x = 5 + 10

5x = 15

x = 3

By putting value of x in equation 1,

2x + y = 5

2 × 5 + y = 5

y = -10 + 5

y = -5

Answer 2

Step-by-step explanation:

X+Y=5........1

2X+Y=10......2

from 1 and 2

3x=15

X=5

Y=0
