she will need 20 pages of stickers 10x20=200 just like 10x18=180 then 20-18=2 pages left

For this case, the first thing we must do is define variables.

We have then:

x: number of pages

y: amount of total stickers

We write the expression that models the problem:

\(y = 10x + 180
\)

For 200 stickers we have:

\(10x + 180 = 200
\)

From here, we clear the value of x:

\(10x = 200 - 180

10x = 20
\)

\(x = \frac{20}{10}

x = 2
\)

Answer:

She needs 2 additional pages of 10 stickers to be able to have 200 stickers in total.
