Indicate which property is illustrated in step 3.
step 1= 12 + 9x - 12 - 4x + 3 = 12 + (9x - 12) - 4x + 3
step 2 = 12 + (-12 + 9x) - 4x + 3
step 3 = [12 + (-12)] + (9x - 4x) + 3
step 4 = 0 + (9x - 4x) + 3
step 5 = (9x - 4x) + 3
step 6 = (9 - 4)x + 3
step 7 = 5x + 3

The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is find the pressure exerted when the temperature of the gas is 380 degrees f show work for the
