Question

If (1,-2) is a solution of equation 2x-y=p, then find yhe value if p​

Answer 1

Step-by-step explanation:

2x-y=p

put x-1,y=-2

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

p=4

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

2x - y = p

x = 1 and y = -2

2 × 1 -( -2) = p

2 + 2 = p

p = 4

value of p = 4
