ok

boys = x girls = y

there are 7 children, 4 boys and 3 girls...

@campbell_st can you show me your solution?

plenty of options...

i find this quite tricky..

two equations two unknowns

if you rewrite Decarts equations you have
y = -1 and 0.5y - x = 1

oh wait. im still trying to figure it out. its tricky :/

- thats probably the best way
i've got a headache trying to create the equations

but we can get them

maybe i need another coffee - lol

brother = x+y sister=x+.5y

.5y when we took one away

sister = 2x+y

brother is actually x+1

x+1brother has x-1+y x-1 being himself

1 + 2x = x + y
where x = girls, y = boys is one equation

x+1+y=y-1+2x

that gives x + 1 = 1 + 2x
giving x=0

i formulated an equation XD
x - 1 = y
y - 1 = x/2

x - 1 = 0.5y is another
so u have
1 + 2x = x + y
x -1 = 0.5y
is that right??

yes that gives x = 3 y=4

oh ok

awesome

x - 1 = y
y - 1 = 0.5x
add
x - 2 = 0.5x
x = 4
y = 4-1 = 3

in your equation x = boys , y = girls right?
yours come out right too

ya and yours is x = girls and y = boys,right?

yea
well done
