Question

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

Answer 1

Answer:

4 is your answer

Step-by-step explanation:

put values of X and y in equation

2*1-(-2)=p

2+2=p

p=4

Answer 2

Answer:

p = 4

x = 1, y = -2

Let's solve this by substituting the values for x and y.

2(1) - (-2) = p

2 + 2 = p

p = 4
