Solve the algebraic expression word problem if there are 15 less boys than girls in a class then how many girls are there in the class

 b+15 = g

Step-by-step explanation:

g = girls

b= boys

t= total students

If you wanted to solve it a different way you would do this:

(b + 15) + b = t

78.59 is the mean

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
