Question

Solve 3p - q = 11 , 3p + q = 1

Answer 1

Answer:

p = 2 and q = -5

Step-by-step explanation:

3p - q = 11 ..........(1)

3p + q = 1 ............(2)

adding equation 1 &2

6p = 12

p = 2

put p = 2 in equation 2

q = 1-6

q = -5

is the answer.

Answer 2

Step-by-step explanation:

here is your answer friend

3p-q=11

3p+q=1

by equating the coefficient

not changing symbols

6p+0=12

6p=12

therefore p=12/6

p=2

putting p= 2 in equation 1

3*2-q=11

-q=11-6

q=-7

therefore p=2 q=-7
