You can put this solution on YOUR website! A math class has 30 students . the number of boys in the class is 4 more than the number of girls.\ Use the system of linear equations to determine the number of girls in the class.
-----------------
Let # of girls be "x".
Then # of boys is "x+4".
--------------
Equation:
x + (x+4) = 30
2x + 4 = 30
2x = 26
x = 13 (# of girls is 13)
