Let's make the number of girls g and the number of boys b.
g%2Bb=466
There are 212 more girls than boys so:
g=b%2B212
If we substitute this value for g into the first equation we get:
%28b%2B212%29%2Bb=466
Get rid of the brackets:
b%2B212%2Bb=466
Add like terms:
2b%2B212=466
Subtract 212 from each side:
2b=254
Divide by 2:
b=127
So the number of boys in the class is 127.
