Question

William is six years older than Robert. In two years, William will be twice as old as Robert. Find their ages.

Answer 1

will=6*rob
will+2=rob*2

solve everything in terms of will
So second equation becomes
will=rob*2-2

then just graph and find intersection graph

Answer 2

I mean solve everything in terms of rob lol sorry

Answer 3

also first line should be will=6+rob not 6*rob

Answer 4

I'm confused....

Answer 5

you can also plug in
will=rob*2-2
into
will=6+rob


it becomes
rob*2-2=6+rob

Answer 6

rob should be 8

Answer 7

oh...

Answer 8

will=6+rob
will+2=rob*2

since rob is 8 you can plug that in for rob

will= 6 + 8 = 14

will is 14

Answer 9

Okay I've got an equation. Let's say Williams age is W and Robert's is R...
(6 + R) + 2 = 2(R +2)
I think that'll help us both. xD

Answer 10

William is six years older than Robert.
w=6+R

In two years, William will be twice as old as Robert. Find their ages.

w*2=2+R

Answer 11

Okay I've got an equation. Let's say Williams age is W and Robert's is R...
(6 + R) + 2 = 2(R +2)
I think that'll help us both. xD

In your equation rob is 4

plug that back in as robert being 4 for

w=6+R

w=6+4 10

I think :)

Answer 12

yes! :DDD I think we've got it!
