Question

if x=a y=b is the solution of the equation x=2+y and x+y=4 then find a and b

Answer 1

⭐Hey here is your answer ⭐

x = a

y = b

if x = 2+y .........(1) eq.

X + Y = 4

putting the value of x from eq.1

x + y = 4

2 + y + y = 4

2y = 4 - 2

y = 2/2

y = 1

Putting the value of y in eq. (1)

x = 2 + y

x = 2 + 1

x = 3

therefore value of x = 3 and y = 1.

and a/c

x = a = 3


y = b = 1

I HOPE IT WILL HELP YOU

thnx for asking Ur questions ✌️✌️

Answer 2

x=2+y here x=a and y=b therefore
a=2+b
x+y=4 here x=a and y=b therefore
a+b=4
=a=4-b
now we put this eq.in 1st equation.
we get:
a=2+b
=4-b=2+b(a=4-b)
=4-2=2b
=2/2=b
=b=1
a=4-b
=4-1
=3
