Answer:

Miki had 288 stickers and Ken had 252 stickers.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

Miki has x stickers.

Ken has y stickers.

The ratio of the number of Miki's stickers to the number of Ken's stickers was 8:7.

This means that \frac{x}{y} = \frac{8}{7}, that is: 7x = 8y, or x = \frac{8y}{7}

After Miki gave Ken 18 of her stickers, they had the same number of stickers.

This means that:

x - 18 = y + 18

x - y = 36

Since x = \frac{8y}{7}

\frac{8y}{7} - y = 36

\frac{8y}{7} - \frac{7y}{7} = 36

\frac{y}{7} = 36

y = 36*7 = 252

And

x - y = 36

x = 36 + y = 36 + 252 = 288

Miki had 288 stickers and Ken had 252 stickers.
