Arianna thinks of a number. "If I double my number and add 6 the answer is 40" Mya thinks of a number. "If I multiply my number by 2 and add 2 the answer is 40"
Marissa thinks of a number. "If I add 6 to my number then divide the result by 2, the answer is 11" Autumn thinks of a number. "If I multiply my number by 3 and subtract 3 then multiply the result by 6, the answer is 3 less than 165"
