Answer 2

Answer:

hey here is your solution

pls mark it as brainliest

Step-by-step explanation:

so here given simultaneous equations are

2x+y=23 (1)

4x+y=19 (2)

subtracting (2) from (1)

we get

-2x=4

ie x=-2

substitute value of x in any of two equations

we get

y=27

hence (x,y)=(-2,27) is solution of above linear equations
