Question

solve 2x+y=10 and 3x-y=5​

Answer 1

Answer:x=3 y= -5

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

Answer:

solve 2x+y=10 and 3x-y=5

solve given two equn is 2x+y-10+3y-y-5

5x = 15

x = 3

put in eqn 1 then

2(3)+y =10

6+y =10

y = 10 -6

y = 4
