Question

Solve x +y = 14 and x - y =2

Answer 1

Answer:

x =8 y = 6

Step-by-step explanation:

x + y = 14

&

x - y = 2

=> x = 2 + y

putting x = 2 + y

we get

=> x + y = 14

=> 2 + y + y = 14

=> 2y = 14 - 2

=> y = 12/2 = 6

so y = 6

&

so x = 2 + y => 2 + 6 = 8

Answer 2

Answer:

x + y = 14 -------- [1]

x - y = 2

Therefore,

x = 2 + y -------- [2]

Using 2 in 1, we have

2 + y + y = 14

2y = 14 - 2

2y = 12

y = 12/ 2

Thus,

y = 6

Put y = 6 in 2

x = 2 + 6

》 x = 8
