How do you solve p - 4 equals -9 p?

Answer 1

13

Answer 2

Put all of the p's to the left of the equal sign and put the number without p to the right of the equal sign. Change from + to - and vice versa when you move something from one side of the = sign to the other.

p-4 = -9p

9p + p = 4

10p = 4

Now divide both sides of the equation by 10.

p = 4/10

Convert to simplest form.

p = 2/5
