Question

Emily and Holly are collecting dolls. They have 39 dolls between them. Write an equation showing this. Emily has 7 fewer than holly write an equation showing this. How many dolls does each girl have?

Answer 1

Let E = # of dolls Emily has, H = # of dolls Holly has

Answer 2

They have 39 dolls between them

so if you add up their individual totals (E and H), you will get 39

this means

E+H = 39

Answer 3

Emily has 7 fewer than holly

which means what?

Answer 4

any ideas?

Answer 5

still cant get it

Answer 6

Emily has 7 fewer than holly

Emily = Holly - 7

E = H - 7

Answer 7

So your two equations are


E+H = 39
E = H - 7

Answer 8

Then you plug in E = H-7 into E+H = 39 to get

E+H = 39

H - 7 + H = 39

2H - 7 = 39

2H = 39 + 7

2H = 46

H = ???

Answer 9

ohh ok thanx

Answer 10

So what do you get for E and H
