Question

5) p= 2x + 3y
Q= 7x + 4y
R=3x + 10y​

Answer 1

Answer:

ANSWER:

We have

(i) 3x + 7x = (3 + 7)x = 10x

(ii) -5xy + 9xy = ( -5 + 9)xy = 4xy

Answer 2

Answer:

mark me as Brilliant ans

Step-by-step explanation:

1. p= 2x+3y

let take the value of x =1

Therefore p = 2 x 1 + 3 y

p = 2 + 3 y

p = 5 y

2. take the value of Y = 2

therefore Q = 7x + 4 x 2

Q = 7x + 8

Q = 15x or Q = -8 -7x

Q = 8 + 7x

Q = 15x

3. take the value of x = -1
