Question #cf085

Answer 1

Three more than twice a number `b` is equal to 24.

`2xxb+3=24`

Now, whatever we do to one side, we do to the other.

Say we subtract 3 from both sides.

`2xxb+3color(red)(-3)=24color(red)(-3)`

`2b=21`

Now, divide both sides by 2.

`(2b)/color(blue)(2)=21/color(blue)2`

`b=21/2`
