If there are 28 students in a class, and there are 6 more boys than girls then howmany girls are there

Question

How would i write a linear equation for this problem

Answer 1

If you let x be the # of girls, then x + 6 = the # of boys

Since the total students = 28, you have x + x + 6 = 28 or 2x + 6 = 28

Solving for x, you have 2x + 6 = 28

2x = 22

x = 11 girls

11 girls + 17 boys = 28 total students
