Sara says, "If you subtract 14 from my number and multiply the difference by - 3, the result is – 42."
Oxana [17]

Answer:

Sara's number is 28

Step-by-step explanation:

Let's assign Sara's number the variable x and solve this equation using the information provided.

"If you subtract 14 from my number"

x - 14

"and multiply the difference by - 3"

-3(x - 14)

"the result is – 42."

-3(x - 14) = -42

Now we can solve from here for x.

-3(x - 14) = -42

x - 14 = 14

x = 28
