Question

8=8p+13-3p
How do you solve this equation?

Answer 1

remember you can do anything to an equaiton as long as you do it to both sides

8=8p+13-3p
group like terms
8=8p-3p+13
add like terms
8=5p+13
minus 13 from both sides
8-13=5p+13-13
-5=5p+0
-5=5p
divide both sides by 5
-5/5=5p/5
-1=1p
-1=p
p=-1

Answer 2

p = -1
8=8p+13-3p
Subtract 8p and 3p
Thats 5p
Now
8=5p + 13
Subtract 13 from 8
-5 = 5p
Divide -5 by 5
-1 = p
