Answer:
-43
Step-by-step explanation:
143 equal number of girls. The boys is unknown so they'll be x and the question says 2 times.So the equation would be 143=57-2x.
143=57-2x
so subtract 57 from both sides (57 and 143).
86=-2x
divide each side by -2
so x= - 43

For example(because I am a bad explainer):
When you divide an exponent by an exponent, you subtract the exponents
For example:
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:
You can think of it like this if you want:
Now multiply the outside exponents into the exponents in the parentheses
Divide 27 and 9
