Question

solve the pair of linear equation by substitution method x minus y equal to 2 and X + Y= 2 also find p if p=2x +3​

Answer 1

Answer:

x=2, y=0, p=7

Step-by-step explanation:

x-y = 2 —(1)

x+y =2—(2)

from (1), x = 2 + y

put in (2) 2+y+y = 2

2 + 2y = 2

2y = 0 y=0

put y=0 in (1)

x-0 = 2

x = 2

Now,

p = 2x+3

p =2(2)+3

p =4+3 =7

p=7

Answer 2

Answer:

Step-by-step explanation:x=2
