Question

Solve : x + y = 6 , x − y = 4​

Answer 1

Answer:

x=5 ,y =1

Step-by-step explanation:

x+y =6

(5)+(1)=6

x-y = 4

(5)-(1)=4

Answer 2

Question:-

Solve : x + y = 6 , x − y = 4

Answer:-

$\huge\pink{\boxed{\blue{\mathcal{{{{\underline{Substitution \: Method}}}}}}}}$

➬ Let x + y = 6 be eq.1

➬ And x − y = 4 be eq.2

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

➦From eq.1 we get

• x + y = 6
• x = 6 - y (eq.3)

______________

➦ Now let us put value of eq.3 in eq.2

• x − y = 4
• 6 - y - y = 4
• 2y = 2
• y = 1 ( eq.4)

=================

➦ Let us put value of eq.4 in eq.1

• x + y = 6
• x + 1 = 6
• x = 5

______________

So the value for x is 5 and y is 1.

Verification:-

• x + y = 6 = (5 + 1) = 6

• x − y = 4 = (5 - 1) = 4
