Question

Solve the pair of linear equations- x-y=2, x+y=4. Also find the value of p if p-2x=3
please answer fast​

Answer 1

Answer:

p = 9

Step-by-step explanation:

x-y=2

x = y + 2------(1)

x + y= 4 --------(2)

substitute (1) in (2)

x + y = 4

y + 2 + y= 4

2y + 2 = 4

2y = 2

y = 1

Substitute y in (2)

x + y = 4

x + 1 =4

x = 3

Given : p-2x=3

           p - 2 (3) = 3

           p - 6 = 3

            p = 9
