What's the problem????
You can solve an eqution - and equation needs an "equality" ( = ) sign - I don't see one anywhere in your post.
Also show us your work/thoughts so that we know where to begin to help you.

If you mean by (m+1)9 distribute it, you can use the distributive property of multiplication over addition.
9m+9 would be what you're looking for, otherwise, you REALLY need to elaborate.

I'll Jump To Conclusions ...
There might be a typographical error. Maybe the expression is actually (m + 19).
I'm only razzing the original poster, here. Okay ... let's see ...
"Simplify the given expression" is a possibility; I've seen this happen before, although I'm not really sure why some instructors teach that 9m+9 is simpler than (m+1)9.
"Use the Commutative Property of Multiplication to rewrite the given expression" is another possibility.
Let's "do" these two.
The Commutative Property of Multiplication says that ORDER does not matter when you multiply two things together.
3 times 5 is exactly the same amount as 5 times 3.
4/5 times 15/2 is exactly the same amount as 15/2 times 4/5
3 * 5 = 5 * 3
(4/5)(15/2) = (15/2)(4/5)
My height times my width is exactly the same bulk as my width times my height.
A times B is exactly the same as B times A
A * B = B * A
(B)(A) = (A)(B)
B * A = A * B
5 * 3 = 3 * 5
? ? (A + B)C has exactly the same value as C(A + B) ? ? hint, hint
Here's a graphic illustration of the Commutative Property of Multiplication -- copyright Paul Griffith 1999, 2002 -- from his interesting page Mathematics Models I
(x + y)z = z(x + y)
(n - 1)8 = 8(n - 1)
and so on ...
Therefore, the answer is 9(m + 1)
Oh, I'm almost out of time.
To "simplify" the expression involves an algebraic concept known as "expansion". Expansion is a process where you carry out as many multiplication operations that you can find in a given expression. Expansion let's you get rid of parentheses, among other things ...
To expand the expression a(b + c) means to carry out all of the multiplications.
Two things are being multiplied together.
a
and
(b + c)
In order to carry out this multiplication algebraically, we use the Distributive Property of Multiplication Over Addition.
a(b + c) = a * b + a * c
One last quick example.
Simplify (i.e., Expand) the expression (n - 1)8.
(n - 1)8 = 8(n - 1)
8(n - 1) = 8 * n - 8 * 1
Expanding (n - 1)8 results in 8n - 8.
Bye!

Is the "it" that you need to "solve" actually the expression in your subject line (that you actually need to "evaluate" or "simplify")?CaliCheer said:
If so, is that expression really "(m + 1)(9) = 9(m + 1)", as you've posted (and as the tutors have, at length, explained), or did you actually mean "(m + 1)[sup:1amg361e]9[/sup:1amg361e]"?
