Answer:
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
