Twice a number and 5 is 15

2x+5=15

Step-by-step explanation:

Are you just supposed to be writing the equation from that information? Let's see what we get and maybe go on from there.

"Twice" means 2 multiplied by,

"a number" is our unknown x,

"and" means add,

"5" is ... well, 5; )

"is" means equals, and

"15" is just 15. Putting that together in an equation looks like this:

2x + 5 = 15.

Now, if you need to find the number, we can do that as well. Subtract 5 from both sides to get

2x = 10 and then divide by 2 to get

x = 5
