Question

Noah started to solve the equation –4.6p – 6.3p + 3.9 = –9.18 below.

Combine like terms: –10.9p + 3.9 = –9.18
Apply the next steps to solve the equation. What is the solution?

p =

Answer 1

Start with -10.9p + 3.9 = -9.18. Subtract 3.9 from both sides:
-10.9p = -13.08.

Divide both sides by -10.9:
p = (-13.08)/(-10.9) = 13.08/10.9 = 1.2.

So p = 1.2.
