Question

the solution of eq x-y = 2
& x+4y is ​

Answer 1

x - y = 2

x = 2+y

put above value of x in the other equa..

x + 4y

2+y + 4y

2+5y ..ans....

Answer 2

Answer:

here is your ans

Step-by-step explanation:

eq 1 = x - y = 2

eq 2 = x + y = 4

we will do by substitution method

from eq 1 , we get

x - y = 2

x = 2 + y -------eq 3

now put the value of x in eq 2 we get ,

x + y = 4

2 + y +y = 4

2y = 4-2

2y = 2

y = 2/2

y = 1

now put the value of y in any of the 3 eqs

we will put in eq 3

x = 2 + y

x = 2 + 1

x = 3

so the solutions of equation x - y = 2 and x + y = 4 are

x = 3

y = 1

hope you understand it

note 1 --- while putting the value of 1st variable it is always advice that put in eq 3 which we have form

note 2 --- this question can be done by 1 more method which is elimination method .
