-5 plus 9n plus 6 is 1 plus 9n.
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
b + 1 is b plus 1 as an algebraic expression.
2m + 1
It is an expression and can be simplified to: 3d+f+1
-5 plus 9n plus 6 is 1 plus 9n.
you have 9n+17=-1 -17 -17 9n=-18 /9 /9 n= -2
Strangely enough, it is 9n + 1 for n = 1, 2, 3, ...
I don't know thats what I'm asking you!
No. 3n isn't a factor of 3n + 7. The GCF of 3n + 7 and 9n is 1.
3(3n - 1)(n + 1)
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
b + 1 is b plus 1 as an algebraic expression.
2!
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
You cannot. What you have in the question is an expression. An expression cannot be proven. You need an equation (or inequality).
The answer is b+1. Therefore the algebraic expression for this is b+1
