Ineed 85 and 86 pleas because i am not in algebra so solve now

85) I gonna do substitution to solve them.

First lets find number of boys.

boys = x

girls = x - 5

27 = x + x - 5 --) 27 = 2x - 5 --) 32 = 2x --) 16 = x

There are 16 boys.

Now do the opposite with girls.

boys = x + 5

girls = x

27 = x + x + 5 --) 27 = 2x + 5 --) 22 = 2x --) 11 = x

There are 11 girls.

86) I gonna do subsitution to solve this problem too.

x + y = 82

6x + 2y = 284

First find # of car magnets

y = -x + 82

6x + 2( -x + 82 ) = 284 --) 6x - 2x + 164 = 284 --) 4x + 164 = 284 --) 4x = 120 --)

x = 30

There are 30 car magnets.

x = -y + 82

6( -y + 82 ) + 2y = 284 --) -6y + 492 + 2y = 284 --) -4y + 492 = 284 --) -4y = -208 --) 4y = 208 --) y = 52

There are 52 bumper stickers

the graph on the bottom right

is there more to this question?
