Stable High School has a total of 112 boys and girls who play sports. If the number of girls, g is 16 more than twice the number of boys, b, how many girls play sports at this high school?
Which system of equations would help you solve this problem?
Answer

b + g = 112
g = 2b + 16

b + g = 112
b = 2g + 16

None of the systems above would solve this problem.

b - g = 112
b = 2g - 16

hi there, so, boys are B and girls are G.  one thing you know is that the total number of students is 112, so, how would you translate that into an equation?

anonymous · Answer

im not sure.... :(

anonymous · Answer

The sum of two things is just A+B

anonymous · Answer

would it be the second one

anonymous · Answer

well forget the multiple choice for a second, let's just develop the equations on our own

anonymous · Answer

ok

anonymous · Answer

b+g=112
g=2b+16

anonymous · Answer

the sum of two things is A+B, and the equals sign means that two things have the same value.  For example, "C=D" means that C and D are the same.  So, the number of boys is B and the number of girls is G, what's the sum of boys and girls?

$$\text{Solve}[\{b+g=112,g=16+2b\},\{b,g\}]$$$$\{b\to 32,g\to 80\} $$
