The equation 4.05p+14.40=4.50 (p+3) represents the number p of pounds of peanuts you need to make trail mix. How many pounds of peanuts do you need to make trail mix?

4.05p+14.40=4.50 (p+3) frist step is to multiple 4.50 to both p+3 so the equation is now 4.05p+14.40=4.50p+7.50 second you want to get on like things to one side does matter which (i will do both so you can see) 4.05p+14.40=4.50p+7.50 - 4.50p - 4.50p the - 4.50p cancels out on this way - 0.45p+14.40=7.50 - 14.40 - 14.40 the - 14.40 cancels out on this way - 0.45p=-6.9 p=-6.9/-0.45 p=15.333333 4.05p+14.40=4.50p+7.50 - 4.05p - 4.05p the - 4.05p cancels out on this way 14.40=.45p+7.50 - 7.50 - 7.50 the - 7.50 cancels out on this way 0.45p=6.9 p=6.9/0.45 p=15.333333 and there is your answer

4.05p+14.40=4.50p+13.50

4.50p-4.50p=13.50-14.40

-0.45p=-0.90

p=-90/-0.45

p=2

You need 2 pounds of peanuts to make trail mix.
