If x=t +12 and t=3p, what property allows you to write the equation x=3p + 12?

Properties of Equations

the reflexive property: for all values of x, we always have x = x;

the symmetric property: if x = y, then y = x;

the transitive property: if x = y and y = z, then x = z.

Step-by-step explanation:

if x=t +12 and t=3p, what property allows you to write the equation x=3p + 12?

here's some instructions

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
