-6 plus 2f plus 3f equals 29 -6 + 2f + 3f = 29 -6 + 5f = 29 5f = 35 f = 7
first place the c's and f's next to each other. 8c-c-3f-3f now 8c-c = 7c and -3f -3f = -6f your answer is 7c-6f Remember that you cannot add of subtract from different letters you can only add of subtract like terms
-2(-3f+6)
What's the question, do you want to simplify that?You can combine the like terms - the terms that contain variable "f". Then, you can either leave it that way, or you can open the parentheses.
It is an algebraic expression which can be simplified if we knew the plus or minus value of 3f which has not been given.
It is an expression and can be simplified to: 3d+f+1

3f+9 = 23 3f = 23-9 3f = 14 f = 14/3 3f+9=23 -9 -9 3f= 14 /3 /3 f= 4.66666 (6 repeats)
The expression is simplified to: 12f-(10a+5b)
It can be simplified to: 4f+2e
