Question

find values of- a)2x+8=y,find y if x=3​

Answer 1

Answer:

step by step explanation

Step-by-step explanation:

given,

p(x)=2x+8=y,

find y=?

if p(x)=3

p(3)=2(3)+8=y

y=6+8=14

Answer 2

Answer:

P(x) = 2x + 8 = y

G(x) = x =3

Putting value of 3 in p(x)

2(3) +8 = y

6 + 8 =y

14 = y

Cross check

Let y = 14

2x +8 = y

2x +8 = 14

2x = 14 - 8

2x = 6

x = 6/2 =3
