Question

If x + y = 12 and x - y= 2. Find x and y.​

Answer 1

Answer:

x + y = 12

let x = 6

and y = 6

then

6+6=12

12=12

Lhs = Rhs

x - y = 2

let x = 4

and y = 2

then

4-2=2

2=2

Lhs = Rhs

Answer 2

• x = 7
• y = 5

Step-by-step explanation:

Given Equations :

• x + y = 12 ....1)
• x - y = 2 ....2)

From equation (1)

x + y = 12

x = 12 - y ....3)

Substituting value of x in Equation (2)

x - y = 2

12 - y - y = 2

12 - 2y = 2

- 2y = 2 - 12

y = 10/2

• y = 5

putting value of y in (3)

x = 12 - y

x = 12 - 5

• x = 7

Hence,

• Value of x = 7
• Value of y = 5
