Question

solve linear quations 2x+y=11 and x+y=8

Answer 1

Step-by-step explanation:

2x+y=11--------(1)

x+y=8-----------(2)

(1)×1=2x+y=11

(2)×2=2x+2y=16

(-) (-) (-)

-------------------------

-y= -5

y=5

putting the value of y in equation (1) we can get

2x+y=11

=> 2x+5=11

=>2x=6

=>x=3

Answer 2

first make eqns

then multiply eqn 2 by 2

2x+2y=16

then subtract 1 from 3

then you get the value of y

then you put this in the eqn 1 or 2 or 3 in which you want the values are same

so you will found the
