The ratio of boys to girls in high school is 4: 7. if there were 300 more girls than boys, how many boys were in school? how many girls?

Step-by-step explanation:

Let G and B be the number of girls and boys.

The ratio boys to girls was 4 to 7.

This means

B/G = 4/7

There were 300 more girls than boys.

This means

G = B+300

Replace in the first equation and solve for B

B/(B+300) = 4/7 ===> 7B = 4(B+300) ===> 7B = 4B + 1200 ===>

===> 7B-4B = 1200 ===> 3B = 1200 ===> B=1200/3 ===> B=400

G = B+300 ===> G = 400 + 300 ===> G=700

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
