Question #334b6

Answer 1

`B=40/3`

`R=52/3`

Explanation:

• `B=` Becky's Age
• `R=`Rob's Age

So

`B=2R-4`

`B+R=48`

Start by substituting. We know that

`48-R=B`

so we can substitute that into the first equation and get

`48-R=2R-4`

Add `R` and `4` to both sides and you get

`52=3R`

So

`R=52/3`

and that can be plugged back into the equation as

`B=2(52/3)-4`

which becomes

`B=40/3`
