Question

Combine like terms: –10.9p + 3.9 = –9.18

Apply the next steps to solve the equation. What is the solution?

Answer 1

p = 6/5

Explanation:

-10.9p + 3.9= -9.18

Times 100

-10.9p • 100 + 3.9 • 100 = -9.18 • 100

Refine

-1090p + 390= -918

Subtract 390 from both sides

-1090p + 390 - 390= -918 - 390

Simply

-1090p = -1308

Divide both sides by -1090

-1090p/-1090 = -1308/-1090

Simply

p = 6/5

Answer 2

p = 1.2

Explanation:

-10.9p + 3.9 = -9.18

When you combine like terms, it becomes

9.18 + 3.9 = 10.9p

13.08 = 10.9p

Now divide both sides of the equation by the number attached to the unknown to get the unknown p

That’s

13.08/10.9 = 10.9p/10.9

1.2 = p

P = 1.2

OR

-10.9p = -9.18 - 3.9

-10.9p = -13.08

Divide both sides by-10.9

-10.9p/-10.9 = -13.08/-10.9

p = 1.2
