The marching band has 85 members. There are 15 more girls than boys in the band. How many boys are in the marching band?

35 boys

(and 50 girls)

Step-by-step explanation:

If b is the number of boys, then the number of girls is b+15

So the sum is b+b+15 = 85

So 2b = 85-15 = 70, so b=70/2=35

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
