Question

Brian was thinking of a number. Brian doubles it and adds 5.1 to get an answer of 91.3. Form

an equation with x from the information.

Answer 1

`2x + 5.1 = 91.3`

Explanation:

x would represent his number. in this case, you double x, because he doubles his number, and then you add 5.1. to solve for x, aka find his original number, you can subtract 5.1 from both sides and then divide by 2. hope this helps!
