F (-2)=8-4×-4=+16
f(x)=8 so 8 =8-4x so x=0
it is liner algebra . I will send you the graph and every thing later . like in 5 min .
8 - 5p = 2 - 3p
Move the terms
= -5p + 3p = 2-8
Collect like terms (calculate)
= -2p = -6
Divide both sides
p = 3 (Final Answer)

Let the unknown number be x.
Given,






x =

= 1.28
Hence, the number is 1.28
