Will give brainliest you in advance!
you are now enrolled in a magic school, and your first assignment is to make up your own number trick. you must also use variable expressions or equations to prove to the other magicians that your trick always works. here is an example trick that you can use for ideas: ask an audience member to select a number from 1 to 10. tell that person to do the following: add 5 to the selected number. double the sum. subtract 4 from that product. divide the result by 2. subtract the selected number from that quotient. dramatically announce that the result is 3. this trick is modeled by the equation [2(x+5)−42]−x=3 open square brackets fraction numerator 2 left parenthesis x plus 5 right parenthesis minus 4 over denominator 2 end fraction close square brackets minus x equals 3 where x x = the selected number. to prove the trick always works, all you have to do is simplify and solve the equation.
