x+x+5+2x+1
a+2a+10-3a
2x+5+2x+1
4x+5+1
4x+6 or 6+4x
I'm pretty sure that's right.
For the second problem, combine like terms. The a's cancel each other out (3a - 3a = 0) leaving you with 10.
Jill is right.
To simplify the expression x + x + 5 + 2x + 1, we can combine like terms, which means combining the terms with the same variable.
First, let's group the terms with the same variable:
x + x + 2x = 4x
Now, let's combine the constants:
5 + 1 = 6
Putting it all together, the simplified expression is:
4x + 6
