please can someone help me with this problem?
the 29 students in a primary school mixed class are all either year 2 students or year three students.
There ar ethe same number of yr two students in the class as as there are boys in the class.
There are 8 yr 2 boys in the class.
the number of yr 3 girls in the class exceeds the number of year 3 boys by 3.
how many yr 3 girls are there in this class?
I already know that I need to use a table for it, but I'm not too sure how to solve it!
any help would be great! thankyou=]
