Question

if (1,-2) is a solution of a equation 2x-y=p then what is p ​

Answer 1

Answer:

2x-y=p

put x-1,y=-2

=2(1)-(-2)=p

p=4

Or

2x-y=p

X=1, Y=-2

Then,

2(1)-(-2)=p

2+2=p

4=p

or

p=4

Hope it will help...!!

Answer 2

Answer:

answer is 4

Step-by-step explanation:

2x - y = p

Now , substituting value of x and y in 2x - y = p

2(1) - (-2) = p

2-(-2) = p

2+2= p

4=p

hope it helps you !!!
