Question

hyun is comparing two numbers. he knows the larger number is twice the value of 4 more than the smaller number, x. he also knows their difference is 11 which equation can he use to find the value of the smaller number x

Answer 1

Let b>a...

b=2(a+4)

b=2a+8  then we are told that:

b-a=11  using b found above in this equation gives you:

2a+8-a=11  combining like terms on left side

a+8=11  subtracting 8 from both sides

a=3

So the smaller number is 3.

...

since b=2a+8

b=14

check..

b=2(a+4)

14=2(3+4)

14=2(7)

14=14

and

b-a=11

14-3=11

11=11
